Among the various TIM options, thermal greases have been widely used for many years due to their low cost and ease of application. However, thermal greases also present well-known reliability and maintenance challenges—particularly in high-power applications. This article introduces a real-world problem-solving example in power conversion equipment, such as inverters, where replacing conventional thermal grease with graphite-based TIM (Graphite TIM) effectively addresses these issues. Thermal Management with Thermal Grease—and Its Limitations Power modules generate significant heat and are typically mounted to heatsinks to dissipate that heat efficiently. In practice, when a heatsink is attached directly to a power module, microscopic gaps inevitably form between the module base plate and the heatsink surface due to slight distortion or unevenness of the base plate. These gaps increase contact thermal resistance, preventing the heatsink from delivering its full cooling potential. To address this, thermal grease is commonly applied between the base plate and the heatsink as a TIM. The grease fills surface irregularities, improving thermal contact and reducing thermal resistance. [Figure 1 – Filling gaps between base plate and heatsink using thermal grease] Despite its widespread use, thermal grease has several inherent drawbacks. Key Issues with Thermal Grease 1. Thermal Resistance Variations Due to Voids Achieving consistent performance with thermal grease depends heavily on application amount and uniformity. Incomplete filling or uneven spreading can leave voids, leading to localized increases in contact thermal resistance and inconsistent heat dissipation. 2. Increased Thermal Resistance Due to Dryout Thermal grease is susceptible to the dryout phenomenon , where exposure to elevated temperatures causes volatile components to evaporate. Over time, oil and filler separate, the grease hardens, and cracks may form. As a result, contact thermal resistance increases. [Figure 2 – Dryout phenomenon illustration] 3. Increased Thermal Resistance Due to Pump-Out During long-term operation, repeated thermal expansion and contraction of the base plate can cause pump-out , in which thermal grease is gradually pushed out from the interface. As the grease layer thins, gaps reappear and thermal resistance rises. [Figure 3 – Pump-out phenomenon illustration] 4. Higher Total Cost of Ownership Although thermal grease itself is inexpensive, mitigating dryout and pump-out requires periodic maintenance. This typically involves disassembly, cleaning, reapplication, and reassembly—adding labor, downtime, and long-term cost. Solving These Issues with Graphite TIM Replacing thermal grease with Graphite TIM , a graphite-based thermal conduction sheet, addresses these challenges effectively. Graphite TIM is a sheet-type TIM with excellent thermal conductivity, designed to be sandwiched between heat-generating components and heatsinks. Panasonic’s Graphite TIM offers high reliability, simple handling, and stable long-term performance. While adequate clamping pressure is required to achieve optimal thermal characteristics, installation is straightforward and repeatable. [Figure 4 – Graphite TIM product image] Performance Comparison: Thermal Grease vs. Graphite TIM The table below summarizes how Graphite TIM resolves the common issues associated with thermal grease. Thermal grease issues Thermal conduction sheet Graphite TIM ① Thermal resistance variation due to voids Absorbs differences in level through its high compressibility, achieving a stable thermal resistance equivalent to that of thermal greases. ② Increase in thermal resistance due to the dryout phenomenon Heat-resistant to temperatures over 400&amp;#186;C; no degradation due to heat ③ Increase in thermal resistance due to the pump-out phenomenon Physical properties remain unchanged semi-permanently. ④ Increase in total costs Easy installation that only requires placement and simple maintenance ⇒ Low total costs [Table 1 – Comparison of thermal grease issues and Graphite TIM features] Void-related thermal resistance variation Graphite TIM’s high compressibility allows it to absorb surface unevenness, providing stable thermal resistance comparable to thermal grease. Dryout-related degradation With heat resistance exceeding 400 &amp;#176;C, Graphite TIM does not degrade due to heat and is unaffected by dryout. Pump-out phenomenon As a solid sheet material, Graphite TIM maintains its physical properties semi-permanently, eliminating pump-out concerns. Total cost Easy installation and minimal maintenance requirements contribute to significantly lower total cost of ownership. Thermal Resistance vs. Pressure Characteristics The graph below shows how the thermal resistance of Graphite TIM changes with applied pressure. [Figure 5 – Thermal resistance vs. pressure graph] As pressure increases, thermal resistance decreases. In high-compression regions, Graphite TIM achieves thermal resistance levels equivalent to thermal grease. This demonstrates that Graphite TIM can be used as a direct replacement without compromising thermal performance. Heat Resistance and Long-Term Reliability An accelerated heat-aging test was conducted to evaluate resistance to dryout. Samples were placed on a 150 &amp;#176;C hot plate for 30 minutes, simulating approximately 10 years of operation. [Figure 6 – Before/after heat aging photos] Unlike thermal grease, Graphite TIM showed no visible degradation or performance loss after the test, confirming its ability to resolve dryout-related reliability issues. Summary Thermal greases have a long history and remain widely used as TIMs, but their susceptibility to dryout, pump-out, and maintenance-driven cost increases presents clear limitations—especially in power electronics. Graphite TIM , as a graphite-based thermal conduction sheet, offers a reliable, maintenance-friendly alternative with stable thermal performance and excellent heat resistance. For power modules and other high-heat applications, it provides a practical solution to the longstanding challenges associated with thermal grease. 8.

These converters are found everywhere—from consumer adapters and chargers to industrial and telecom power systems. As product designers pursue smaller size, higher efficiency, and better thermal performance , conventional silicon (Si) switching devices are reaching their physical limits. This is where gallium nitride (GaN) power devices are rapidly gaining adoption. [Figure 1: Examples of AC/DC converters used in home and office applications] Unlike traditional Si devices, GaN switches significantly faster and with lower switching loss. This enables: Higher switching frequencies Reduced heat generation Smaller passive components Higher power density without sacrificing efficiency As a result, GaN has become a key enabler for next‑generation compact AC/DC converter designs, particularly in notebook adapters, USB‑PD chargers, and industrial power supplies. GaN vs. Silicon: Switching Loss and Frequency Advantages The most important advantage of GaN lies in its low switching loss at high frequencies . While conventional Si devices typically operate around 100 kHz, GaN devices can comfortably switch in the 200 kHz to 500 kHz range while maintaining high efficiency. [Figure 2: Switching waveforms comparison – GaN vs. Silicon] At higher switching frequencies: Magnetic components (inductors, transformers) can be smaller Output capacitors must handle higher ripple current frequencies Component selection becomes critical for maintaining low ripple voltage This shift in operating frequency fundamentally changes the requirements for output capacitors. The Role of Output Capacitors in High‑Frequency AC/DC Designs The output capacitor plays a vital role in smoothing the DC output by absorbing ripple current generated by switching operation. The resulting ripple voltage must remain within strict limits—typically less than &amp;#177;5% of the output voltage —to ensure stable system operation. [Figure 3: Output ripple voltage concept and waveform] The ripple voltage relationship is straightforward: ΔV = ΔI &amp;#215; Z Where: ΔV is ripple voltage ΔI is ripple current Z is the impedance of the capacitor at the switching frequency Therefore, low impedance at high frequency is the key requirement for output capacitors in GaN‑based AC/DC converters. Why Polymer Capacitors Outperform Electrolytic Capacitors with GaN Traditional liquid electrolytic capacitors struggle at high switching frequencies due to increasing impedance. In contrast, Panasonic solid polymer capacitors exhibit extremely low impedance in the 100 kHz to 1 MHz range, making them ideal for GaN power supplies. [Figure 4: Impedance vs. Frequency – Polymer vs. Electrolytic Capacitors] This performance advantage comes from Panasonic’s low‑ESR conductive polymer electrolyte technology , which delivers: Much lower ESR than liquid electrolytic capacitors Superior ripple voltage suppression Excellent high‑frequency characteristics As a result, polymer capacitors can achieve the same—or better—ripple performance with significantly smaller capacitance values , enabling further downsizing. High Ripple Current Capability and Thermal Stability Low ESR not only reduces ripple voltage but also allows polymer capacitors to tolerate higher ripple currents without excessive self‑heating. In addition, because the electrolyte is solid rather than liquid, Panasonic polymer capacitors offer: Stable performance at low temperatures No electrolyte drying or leakage Minimal ESR degradation over long operating life [Figure 5: Ripple current vs. self‑heating, ESR vs. temperature, and endurance characteristics] These characteristics are especially valuable in industrial and telecom applications where long life and wide temperature operation are mandatory. Real‑World Comparison: Polymer vs. Electrolytic Capacitors in a GaN AC/DC Converter To illustrate the impact in practice, consider a high‑frequency AC/DC converter operating between 200 kHz and 400 kHz . Test Overview Output power: 150 W Output voltage: 48 V Allowable ripple: &amp;#177;400 mV Operating temperature: –30 &amp;#176;C to +65 &amp;#176;C Expected lifetime: 50,000 hours Capacitor Comparison Electrolytic: 63 V, 390 &amp;#181;F &amp;#215; 3 Polymer: 63 V, 33 &amp;#181;F &amp;#215; 1–3 [Figure 6: Capacitor characteristic comparison] Even though the conductive capacitor has a smaller capacitance, its excellent frequency characteristics suppress ripple voltages to the same level. ↓ When looking at the lowest operating temperature -30&amp;#176;C, it shows a possibility to design only with a single conductive capacitor. And this will be stable even at the end of life (after 50,000 hours). = Reduced mounting area / cost / longer life [Figure 7: Output ripple voltage comparison results] Key Results At low temperature (–30 &amp;#176;C), a single polymer capacitor achieved 47% lower ripple voltage than the electrolytic solution At room temperature, polymer capacitors delivered comparable ripple performance with only 1/10 the capacitance No low‑temperature degradation, unlike electrolytic capacitors Result: ✅ Reduced mounting area ✅ Lower component count ✅ Longer operational life ✅ Improved reliability Panasonic Polymer Capacitor Portfolio for GaN Power Supplies Panasonic offers one of the industry’s most comprehensive polymer capacitor lineups, supporting voltages up to 100 V and optimized for high‑frequency power conversion.

Panasonic’s Capacitors, Inductors, and Resistors Are Transforming the Future of EVs, E‑Bikes, AGVs, and Automotive Power Electronics. Introduction As global transportation accelerates toward electrification, automation, and higher power density, electronic designers face increasingly complex challenges. Whether it’s the rapid growth of electric vehicles, the explosion of the e‑bike market, or the expansion of industrial AGVs and next‑generation train systems, one truth remains constant: reliable passive components form the backbone of every mobility innovation . Panasonic’s portfolio of high‑performance passive components—spanning hybrid capacitors, metal‑composite inductors, precision resistors, and automotive‑grade reliability solutions—enables engineers to design systems that are safer, more efficient, and built to withstand harsh real‑world environments. This article explores how Panasonic’s component technology directly addresses the toughest design constraints in modern mobility and why these components have become a trusted choice among engineers designing for EVs, e‑bikes, AGVs, and power electronics. 1. Evolving Market Demands in the Transportation Sector Electrification Is Redefining Component Requirements Today’s transportation ecosystem includes everything from passenger EVs and commercial vehicles to agricultural machinery, e‑bikes, and automated guided vehicles. As power systems shift from mechanical to electric, passive components must handle significantly higher electrical stress and environmental demands. Key drivers reshaping component specifications include: Automotive Electrification Gasoline vehicles: primarily mechanical → require high‑reliability components Electric vehicles (EVs): motor‑driven → need high reliability plus high current capability Rapid Expansion of the E‑Bike Market Motor output increasing: 500 W → 750 W+ System voltages rising: 36 V → 48 V / 60 V Compact, multifunctional designs becoming standard Core Requirements Across Transportation Systems To support these trends, designers now prioritize: High current capability (low DCR, low ESR to improve efficiency) Thermal robustness (–55 &amp;#176;C to +170 &amp;#176;C operating range) Miniaturization &amp;amp; high density (SMD formats, compact power modules) EMI suppression (especially for motor‑drive and switching circuits) Long operational life (10+ years demanded in EV/AGV applications) These requirements form the foundation for why Panasonic’s passive components—especially its hybrid capacitors , metal composite inductors , and automotive‑grade resistors —have become essential solutions for next‑generation mobility systems. 2. Hybrid Capacitors: Panasonic’s High‑Performance, Long‑Life Solution for Modern Mobility Panasonic’s hybrid capacitors are engineered to meet the rapidly intensifying demands of transportation electronics. By combining the strengths of electrolytic and polymer capacitor technologies, Panasonic delivers a balance of high ripple current , long operational life , and failsafe reliability —attributes essential in EVs, e‑bikes, AGVs, and automotive power electronics. Hybrid capacitors have become one of the most impactful innovations in Panasonic’s passive component lineup, enabling compact, thermally robust, and electrically stable designs for high‑power mobility systems. 2.1 Technical Challenges in Transportation Power Systems Designers working on EV inverters, DC‑link circuits, e‑bike motor drivers, and industrial AGVs face several recurring challenges: High Current Handling Requirements E‑bike and AGV platforms demand DC‑link capacitors capable of managing 20–60 A ripple currents —especially in systems ranging from 500 W to 6 kW . Conventional aluminum electrolytic capacitors often require multiple parts in parallel, consuming valuable PCB area and increasing BOM cost. Long‑Term Reliability Under Extreme Conditions Modern EVs and AGVs require product lifetimes of 10 years and operating endurance exceeding 4,000 hours at 125 &amp;#176;C , far surpassing the typical 2,000‑hour rating of general electrolytic capacitors. This creates a significant reliability gap traditional technologies cannot bridge. Fail‑Safe Behavior in Failure Modes Polymer capacitors can offer low ESR and high current handling but risk short‑circuit failure , which is unacceptable in safety‑critical automotive and industrial systems. Regulations require open‑circuit failsafe behavior to prevent secondary damage or thermal hazards. Panasonic’s hybrid technology directly addresses all three challenges simultaneously. 2.2 Panasonic Hybrid Capacitor Technology Panasonic’s hybrid capacitors merge liquid electrolyte with conductive polymer to create a component category that excels in both performance and safety . Key Advantages (Example: 35 V 47 μF device) Low ESR rivaling polymer capacitors → dramatically improved ripple current capability Open‑circuit fail‑safe behavior like aluminum electrolytics → enhanced safety margin Double the operational life compared with conventional capacitors Up to 4.5&amp;#215; higher ripple current tolerance for high‑power converters This allows engineers to reduce component count, shrink board size, and enhance system reliability—crucial benefits in compact traction inverters and motor‑control units. 2.3 Key Hybrid Capacitor Series for Transportation Panasonic offers multiple hybrid capacitor families tailored for different mobility applications: Series Capacitance Ripple Current Miniaturization ZTU Up to 1.7&amp;#215; larger than entry‑level hybrids (e.g., 330 &amp;#181;F → 560 &amp;#181;F, φ10&amp;#215;10.2 mm) 1.8&amp;#215; improvement (2900 mA → 3500 mA) Smaller case option: φ10&amp;#215;10.2 → φ8&amp;#215;10.2 ZUU Highest capacitance class, up to 1000 &amp;#181;F Industry‑leading ripple current up to 6100 mA Enables 1‑to‑many replacements to reduce cost/space ZVU 1.7&amp;#215; capacity increase compared to ZC series Maintains high ripple current similar to ZV (up to 4.6 A in 10&amp;#215;10.2 mm) Supports design consolidation &amp;amp; PCB reduction Series Highlights ZTU : Build higher capacity or achieve miniaturization ZUU : Best for high ripple current + ultra‑high capacitance ZVU : Higher capacitance while keeping low‑profile packaging These series are widely used in EV power steering, cooling fans, OBCs, and e‑bike motor drives. 2.4 Application Example: E‑Bike 6 kW Drive Inverter System Overview 48 V Li‑ion Battery → DC‑DC Converter → BM‑IC → Motor Drive Inverter Conventional Design 12 &amp;#215; 63 V, 150 μF, φ10 &amp;#215; 16.5 mm Proposal 1 (Using ZUU Series) 63 V, 180 μF &amp;#215; 8 pcs (φ10 &amp;#215; 16.5 mm) Total Capacitance: 1,440 μF Ripple Current: 44 Arms Component reduction: –33% Proposal 2 (ZUU Low‑Profile Option) 63 V, 120 μF &amp;#215; 9 pcs (φ10 &amp;#215; 12.5 mm) Height reduced 16.5 mm → 12.5 mm (–24%) Ideal for compact e‑bike frames and integrated motor systems 2.5 Automotive Example: Electric Power Steering (EPS, 12 V / 500 W) Conventional Design 4 &amp;#215; 25 V, 470 μF, φ10 &amp;#215; 12.5 mm Panasonic ZUU Proposal 25 V, 1000 μF &amp;#215; 2 pcs (φ10 &amp;#215; 16.5 mm) Total Capacitance: 2,000 μF (+6.4%) Ripple Current: 12.2 Arms Component count reduced by 50% 2.6 Automotive Example: Cooling Fan (24 V / 4 kW, 3‑Phase Motor) Conventional Design 35 V, 470 μF &amp;#215; 11 pcs (φ10 &amp;#215; 16.5 mm) ZUU Proposal 35 V, 680 μF &amp;#215; 9 pcs Total Capacitance: 6,120 μF (+18%) Component reduction: –18% 2.7 Automotive OBC DC‑DC Converter (400 V → 12 V) Conventional Design 25 V, 470 μF &amp;#215; 8 pcs (φ10 &amp;#215; 10.2 mm) ZV Series Proposal 25 V, 330 μF &amp;#215; 5 pcs (φ10 &amp;#215; 10.2 mm) Component count reduced by 38% Maintains equivalent electrical performance thanks to low‑ESR characteristics 3. Power Inductors: Panasonic’s Metal Composite (MC) Core Technology for High‑Current, Low‑EMI Mobility Systems Power inductors are central to every high‑efficiency power conversion stage found in electric vehicles, e‑bikes, AGVs, battery management systems, and compact industrial drives. As system voltages rise and switching frequencies increase, passive magnetic components must deliver higher current , lower EMI , and greater thermal stability —all within increasingly compact mechanical footprints. Panasonic’s proprietary Metal Composite (MC) Core inductors are engineered precisely for these next‑generation requirements. By combining advanced materials science with robust structural design, Panasonic creates inductors that offer exceptional current capability , low DC resistance , minimal magnetic flux leakage , and industry‑leading thermal performance , enabling designers to optimize power density without compromising reliability. 3.1 Key Technical Challenges in Modern Mobility Designs As mobility platforms move toward higher power and higher switching frequencies, traditional ferrite-core inductors encounter several limitations. Panasonic’s MC-core technology directly addresses these challenges. EMI Mitigation &amp;amp; Magnetic Noise Reduction E‑bikes, AGVs, and compact EV systems employ fast-switching MOSFET/SiC power stages that generate high-frequency electromagnetic noise. Ferrite inductors typically exhibit high leakage flux , making compliance with EMC regulations more difficult. Panasonic MC inductors dramatically reduce radiated noise through a dense metal‑composite material structure that naturally suppresses flux leakage—greatly simplifying EMC countermeasures. Miniaturization Constraints As system voltages grow to 48–60 V and beyond , inductors must handle 5 A+ continuous currents without requiring larger, bulkier components. Ferrite cores saturate sharply, limiting their downsizing potential. MC-core inductors allow engineers to reduce size while supporting higher currents, maintaining stable inductance even during transient loads. Thermal Management &amp;amp; High‑Temperature Reliability In harsh automotive environments—near motors, inverters, or engine compartments—temperatures frequently exceed 100 &amp;#176;C . Heat causes drift in inductance, impacts efficiency, and accelerates component aging.

higher‑level autonomous driving, the Domain Control Unit (DCU) has become a central element of next‑generation vehicle architecture. DCUs consolidate data from multiple sensors, make real‑time decisions, and coordinate critical control functions—requiring components that deliver high current capability, low loss, miniaturization, and excellent EMC robustness . This technical guide provides an engineer‑friendly explanation of DCU roles, system configurations, and design challenges—and showcases how Panasonic Industry components support reliable, high‑performance DCU development. If you&amp;#39;re designing automotive ECUs, power modules, or sensing interfaces, this guide will help you choose optimal Panasonic devices for your next project. 1. ADAS vs. AD: Why DCUs Are Increasing Rapidly Advanced Driver Assistance Systems (ADAS) support the human driver, while Autonomous Driving (AD) shifts responsibility to the vehicle itself. According to SAE levels: Level 0–2: Human‑driven with partial assistance Level 3–5: Vehicle executes most or all driving tasks As vehicles progress into Level 3 and beyond, the sensor count and data throughput grow dramatically. This makes centralized processing , fast communication , and robust power management more critical—hence the rapid adoption of DCUs. Level Name Driven by Driving area Remarks 0 No driving automation Human driver － The human performs all driving tasks 1 Driving assistance Human driver Limited Provides driving assistance in part through tasks such as monitoring the vehicle&amp;#39;s perimeter 2 Partial driving automation Human driver Limited &amp;quot;Hands off&amp;quot; - Automates driving under specific conditions 3 Conditional driving automation Vehicle Limited &amp;quot;Eyes off&amp;quot; - Automates driving under specific conditions 4 Advanced driving automation Vehicle Limited &amp;quot;Brain off&amp;quot; - Automates driving under specific conditions 5 Full driving automation Vehicle No limitations The vehicle performs all driving tasks under all conditions Table 1 Definition of autonomous driving by level 2. Core System Blocks Required for ADAS / AD A complete sensing‑to‑control chain typically includes: Sensor ECU Cameras, RADAR, LiDAR, and ultrasonic sensors gather environmental data. Main ECU / DCU Performs high‑speed data fusion, perception, and decision‑making. Actuator ECU Controls braking, steering, powertrain, and other vehicle dynamics. A DCU sits at the heart of this system, enabling seamless communication between domains and ensuring reliable autonomous operation. Figure 1 Overall system flow (from sensing to operation) 3. Domain vs. Zone Architecture—Where DCUs Fit As OEMs evolve their E/E architectures, two major approaches are used: Domain Type (Distributed) Each function (ADAS/AD, powertrain, body, cockpit, etc.) has its own DCU Processing is performed inside each domain Domains communicate via gateway ECUs Ideal for: Level 2 and Level 2+ applications Zone Type (Centralized) ECUs grouped by vehicle location (front, rear, cabin) A central computer consolidates all zone‑level inputs Supports massive data throughput and high compute requirements Ideal for: Level 3–5 and next‑generation EV platforms Configuration Connection Network Domain type Consolidates domain-specific ECUs for each category (domain) All domains are connected via the Gateway Data processing is performed in each domain-specific ECU Common network standards are used for communication between sensors and domains Common network standards are used for communication between the domains and Gateway Zone type Consolidates ECUs of different categories in each zone such as the front and rear of the vehicle Consolidates data from each zone to the Central Computer Integrates and concentrates data processing in the Central Computer There is a mixture of different network standards for communication between sensors and zones Common network standards are used for communication between the zones and Central Computer 4. What Exactly Does a DCU Do? A DCU integrates multiple functions: High‑speed communication with sensors and other ECUs Data fusion and environment recognition using SoCs and dedicated processors Memory management (Flash, DDR) for algorithms and sensor data Power management through multiple isolated DC/DC converters Command execution to actuators and cooperating domains This makes DCUs one of the most component‑dense areas in modern automotive electronics. 5. Component Requirements for High‑Performance DCUs DCUs demand components with: High current tolerance for heavy processing loads Low loss to minimize thermal buildup High‑frequency capability for switching and communication Miniaturization for dense board layouts Highly stable voltage characteristics Panasonic Industry specifically develops components aimed at fulfilling these stringent requirements. 6.

What Types of Cameras Are Used in ADAS and AD Systems? Automotive cameras are essential sensing devices that help vehicles interpret their surroundings. In both Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD), cameras work alongside radar, LiDAR, and ultrasonic sensors to build a multi‑directional understanding of the environment. Modern vehicles typically integrate three primary camera categories : • Sensing Cameras (Forward‑Facing) Mounted near the top of the windshield, these cameras monitor a wide forward area to support key safety functions such as lane keeping, lane changing, traffic sign detection, and automatic emergency braking. • Surround View Cameras Installed at the front, rear, and both sides of the vehicle body, these cameras capture near‑range images to create a 360&amp;#176; view. They support parking assist and low‑speed maneuvering. • Driver Monitoring Cameras Positioned near the instrument cluster, these cameras track the driver’s condition, including eye closure, gaze direction, and signs of drowsiness or inattention. Each camera type serves different operational goals, yet all contribute to safer, more automated driving experiences. 2. Uses and Functions of Each Camera Type Different ADAS/AD features depend on specific camera modules. Below is an overview of their major applications: Sensing Cameras Used for decision‑making and control actions: Lane Keep Assist (LKA) Lane Change Assist (LCA) Autonomous Emergency Braking (AEB) Forward collision avoidance Traffic sign recognition These cameras play a central role in higher‑level AD systems where precise object detection and classification are essential. Surround View Cameras Primarily used for: Parking assistance Close‑range obstacle detection Surround visualization in the cockpit display These cameras help drivers—and autonomous systems—understand vehicle positioning in tight spaces. Driver Monitoring Cameras (DMS) Used for: Assessing the driver’s alertness Detecting fatigue or inattention Monitoring head pose and gaze direction As global regulations evolve, DMS is becoming mandatory in many markets. 3. Internal Configuration of Automotive Cameras Although sensing, surround view, and driver monitoring cameras differ in purpose, their internal architectures share common building blocks. Sensing Cameras &amp;amp; Driver Monitoring Cameras These modules typically include: Image Sensor – Converts incoming light into electrical signals. SoC (System-on-Chip) – Performs image analysis, object recognition, and high-speed processing. MCU – Issues control commands to external ECUs. Transceiver – Handles data communication with ADAS/AD ECUs. DDR Memory – Provides high‑speed data buffering. Flash Memory – Stores firmware and calibration data. Surround View Cameras This type uses multiple image sensors , each positioned around the vehicle. Captured images are transferred to a Surround View ECU , where an FPGA or high‑performance SoC synthesizes them into a single omnidirectional view. Because of the volume of image data involved, communication bandwidth and processing speed are especially critical. 4. Market Trends and Camera Module Requirements With increasing vehicle production and the rapid evolution of autonomous driving, camera units are expected to grow in both quantity and capability. Future camera modules are increasingly driven by three major performance demands: 4.1 Higher Power Capability Rising image sensor resolutions Higher dynamic range performance More advanced SoCs requiring substantial computational power These factors raise internal losses and thermal loads, demanding high‑current, low‑loss components. 4.2 Higher‑Speed Data Transmission As image data volumes grow, communication interfaces require: High‑frequency performance Low‑parasitic components High‑speed EMI/ESD protection Automotive Ethernet and other high‑rate protocols rely heavily on robust passive components. 4.3 Miniaturization and Weight Reduction Compact camera modules reduce vehicle weight, simplify mounting, and enhance design flexibility. Achieving this requires smaller yet more capable capacitors, inductors, and resistors. 5. Circuit Configuration of Each Camera Module The following components constitute the core circuitry of sensing and driver monitoring cameras: • Image Sensor Captures visual data and converts light into electrical signals. • SoC Processes images, performs recognition algorithms, and generates control outputs. • MCU Handles operational commands and coordinates with system‑level ECUs. • Transceiver (High‑ and Low‑Speed) Supports communication with other vehicle systems. • DDR Memory Acts as a buffer for real‑time image processing. • Flash Memory Stores firmware, system configuration, and calibration parameters. • DC/DC Converters Provide regulated voltages for image sensors, memory, SoCs, and communication ICs. These power stages must address noise suppression, fast transient response, and minimal ripple to prevent image degradation. Surround view camera A camera ECU and surround view ECU are used to make up a surround view camera. Unlike other types of camera modules, multiple camera units are mounted on a vehicle to make up the surround view camera. Therefore, transceiver circuits must communicate larger amounts of data. An FPGA is used to integrate the acquired image data into one, where image processing is performed at high speed. Other configurations are the same as those of sensing cameras and driver monitoring cameras. 6.

Thank you very much for your comment! It cannot be said that there are no errors, but we believe the probability is low. The transmission and reception of the laser are synchronized, so reception data at different timings are unlikely to be processed. Even if there are a few errors, I think they wouldn&amp;#39;t pose a problem for safety assessments. Additionally, ADAS does not rely solely on LiDAR for safety judgments, so I believe there is no issue.</description></item><item><title /><link>https://community.element14.com/products/manufacturers/panasonic/b/blog/posts/lidar-technology-in-autonomous-driving-a-practical-guide-to-key-components?CommentId=8057419b-0b60-4624-8940-4191fb60c1c8</link><pubDate>Wed, 04 Feb 2026 13:58:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:8057419b-0b60-4624-8940-4191fb60c1c8</guid><dc:creator>robogary</dc:creator><description>I always wondered if every vehicle in traffic had lidar would they crosswalk and create errors, or is it like FHSS, the chance of detecting pulses from a different source are unlikely to align time wise, or maybe the lidar pulse is an encoded burst ?</description></item><item><title /><link>https://community.element14.com/products/manufacturers/panasonic/b/blog/posts/lidar-technology-in-autonomous-driving-a-practical-guide-to-key-components?CommentId=bf4cce52-9174-4d26-b961-990962c71597</link><pubDate>Tue, 03 Feb 2026 19:58:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:bf4cce52-9174-4d26-b961-990962c71597</guid><dc:creator>DAB</dc:creator><description>Yes LIDAR has come a long way since I was first involved with it many decades ago.</description></item><item><title>Blog Post: LiDAR Technology in Autonomous Driving: A Practical Guide to Key Components</title><link>https://community.element14.com/products/manufacturers/panasonic/b/blog/posts/lidar-technology-in-autonomous-driving-a-practical-guide-to-key-components</link><pubDate>Tue, 03 Feb 2026 01:47:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:dcbf5ab0-d4e7-4897-b52f-6edc6501cd45</guid><dc:creator>riyo@panasonic</dc:creator><description>1. What Is LiDAR? LiDAR (Light Detection and Ranging) is a sensing technology that measures the distance to objects by emitting laser pulses and capturing the reflected light. The combination of emission direction and time‑of‑flight enables the generation of a high‑resolution 3D point cloud, which is widely used in ADAS and autonomous driving systems. As vehicle automation advances, the adoption of LiDAR is expected to grow steadily. Optical element Optical axis varying method Type Scanning LD, PD Mechanical method Rotation by a motor A number of LDs and PDs are rotated by a motor to scan the whole area. Polygon mirror Respective optical axes of a single LD and a single PD are varied by a polygon mirror in scanning. Non-mechanical method (solid-state) MEMS mirror Respective optical axes of a single LD and a single PD are varied by a MEMS mirror in scanning. Phased array Respective optical axes of a single LD and a single PD are varied by a waveguide in scanning. Flash Light from a light source, such as an LED, is emitted over a wide area, and reflected light is collectively scanned by an array of PDs. 2. How LiDAR Measures Distance and Recognizes Objects Distance Measurement A laser diode emits a pulse toward an object. A photodiode receives the reflected light. The distance is determined from the time between emission and reception. Object Recognition By repeatedly scanning in multiple directions, LiDAR creates a point cloud. This data is used to: Identify obstacles Build dynamic 3D maps Estimate and correct the vehicle’s position in real time 3. Market Trends and Technical Requirements As autonomous driving levels increase, LiDAR systems must meet three key requirements: Requirement Reason Higher power Higher‑resolution sensing increases CPU load and power demands. Faster communication High‑frequency and high‑speed data transfer is essential to process large point clouds. Smaller size &amp;amp; lighter weight Vehicles incorporate more sensors, requiring miniaturized components. 4. LiDAR System Overview A LiDAR unit typically consists of: Laser Diode (LD) : Emits high‑speed laser pulses Photodiode (PD) : Converts received light into electrical signals Amplifier for the PD output FPGA : Handles high‑speed data processing MCU : Controls system operation Transceiver : CAN/Ethernet communication DDR &amp;amp; Flash Memory DC/DC Converters : Provide necessary voltage rails 5.

Transceiver Interface (CAN / Ethernet) Because communication lines are exposed to ESD, protection devices are critical. Recommended Components Chip varistor ESD suppressor (ultra‑low capacitance) Key points: Chip varistors cover a wide capacitance range (8–250 pF) for low → high‑speed communication ESD suppressors (0.1 pF) are optimal for high‑speed interfaces 5‑3.

Recommended Components High‑precision chip resistor → Sets amplifier gain NTC thermistor → Temperature compensation Why they matter: Low‑TCR thin‑film resistors ensure stable gain High‑reliability thermistors maintain accurate sensing across temperatures 5‑4. Laser Diode Irradiation Circuit A GaN FET is typically used to deliver high‑speed, high‑power pulses. Recommended Components Small, high‑power chip resistor (gate resistor) Key advantage: Original resistance pattern and electrode design support high‑power switching while enabling device miniaturization 6.

Guide to Panasonic Industry Chip Resistors As electronic devices continue to shrink while delivering ever-greater performance, thermal design has become one of the most critical—and often underestimated—challenges in circuit development. Highly integrated ICs and densely packed surface‑mount components generate more heat than ever before, placing new demands on designers tasked with ensuring long‑term reliability. To address these challenges, Panasonic Industry promotes a design approach that is rapidly becoming essential in advanced PCB development: terminal‑temperature‑based power rating . This technique provides far more accurate guidance than traditional ambient‑temperature‑based ratings—especially for today’s compact SMD resistors. In this article, we explain why terminal temperature matters, how to measure it correctly, how international standards (including JEITA) are evolving, and how Panasonic’s chip resistors can help ensure reliable, thermally sound circuit performance. 1. From Leaded Components to SMD: Why Thermal Behavior Has Changed Historically, through‑hole (leaded) resistors dissipated most of their heat—up to 90%—directly into the surrounding air. Their rated power was therefore determined with ambient temperature as the reference point . Today’s electronics, however, rely heavily on surface‑mount resistors , which behave very differently: Leaded Resistors Large surface area → excellent heat dissipation through convection and radiation Minimal heat transfer to the PCB Ambient temperature is the dominant variable Heat effect image of resistor with leads With thin and long lead terminals, the component conducts (releases) a small amount of heat to the mounting board. The large surface area of the component allows for great convection, radiation, and dissipation of heat. Surface‑Mount Chip Resistors Very small surface area → limited convection and radiation Large solder‑pad contact area → significant heat conduction into the PCB Strongly affected by neighboring components’ heat Because SMD resistors experience heat not only from their own power dissipation but also from the board, relying solely on ambient temperature can lead to significant errors in power‑rating calculations. Heat effect image of surface-mounted component Having connection terminals with a large contact area, the component conducts (releases) a large amount of heat to the mounting board. The small surface area of the component lessens the ability of convection, radiation, and dissipation of heat. 2. Why Terminal‑Temperature‑Based Specification Is Becoming Essential To solve this mismatch, manufacturers—including Panasonic Industry—have adopted a more precise method: measuring power rating based on terminal temperature rather than ambient air temperature. This approach allows engineers to: Quantify the exact thermal load applied to a resistor during operation Reduce design uncertainty caused by complex heat flow within a dense PCB Improve prediction accuracy for component lifetime and failure risk The trend has grown strong enough that industry organizations such as JEITA have begun issuing study reports and guidance documents, including RCR‑2114: Study for the derating curve of fixed surface‑mount resistors , which Panasonic follows when defining its product specifications. 3. Measuring Terminal Temperature: Methods and Key Considerations Terminal temperature can be measured using two common tools: Method Advantages Limitations Thermocouple High accuracy, direct measurement Requires physical contact; heat conduction through wires may distort readings Infrared thermography Contactless, easy to use, wide temperature range Cannot measure through glass; requires high surface emissivity (may need black coating) Because many practical evaluations occur at the prototype stage and involve very small components, thermocouples are the most commonly used tool . 3.1 Choosing the Right Thermocouple Thermocouples vary in heat conductivity and measurement characteristics: K‑type Ideal for chip resistors due to low heat conductivity and minimal thermal interference. T‑type Highly accurate but conducts heat more easily, which can artificially lower the reading on small components. For reliable results, selecting a thermocouple with thin wires and low thermal mass is essential. 3.2 How to Prepare and Attach a Thermocouple Correctly To ensure accurate readings: Properly weld the wire tips Twisting or soldering the wires together is not enough Use spot‑welding to form a small, stable junction Avoid oversized or crossed wire tips An oversized joint or a stray wire can act as a heat sink This causes temperature readings to fluctuate or drop artificially Attach precisely to the center of the solder fillet Placing the junction near the edge or outside of the fillet compromises accuracy The thermocouple must be exactly at the intended thermal reference point Panasonic’s evaluation examples emphasize correct positioning, as shown in their measurement diagrams. 3.3 Sources of Measurement Error Even when the thermocouple is attached correctly, two main factors may introduce errors: Lot‑to‑lot inconsistency in the thermocouple’s electromotive characteristics Voltage measurement error in the data logger (channel‑to‑channel variation) Engineers should always account for these factors when interpreting measurement results. 4. Selecting Components Based on Terminal‑Temperature Rating Panasonic Industry provides both ambient‑temperature‑based and terminal‑temperature‑based ratings in many resistor datasheets. A sample from the ERJPA3 (0603) series illustrates how both specifications coexist: Ambient‑Temperature‑Based Derating Example 105 &amp;#176;C → 100% rated power 135 &amp;#176;C → 40% rated power Terminal‑Temperature‑Based Derating Example 130 &amp;#176;C → 100% rated power 135 &amp;#176;C → 80% rated power In cases where both ratings are listed and the design environment is complex (high density, high heat flow), Panasonic recommends prioritizing the terminal‑temperature‑based rating for greater design accuracy. 5. Why This Matters for Today’s Designers As electronics continue to evolve toward higher power density and smaller footprints, thermal reliability becomes a determining factor in product lifespan and performance. Terminal temperature offers a more reliable metric than ambient conditions, especially for SMD resistors mounted on densely populated PCBs. Key takeaways: SMD resistors experience significantly more board‑influenced heating than leaded components Terminal‑temperature‑based rating produces more accurate real‑world load calculations Using the correct thermocouple and attachment technique is critical to obtaining reliable data Panasonic Industry provides clear, JEITA‑aligned specifications to support accurate thermal design Explore Panasonic Chip Resistors on Farnell Panasonic Industry offers a broad lineup of high‑reliability chip resistors engineered for stable performance under demanding thermal conditions.

By using millimeter-wave radio signals, radar detects objects and obstacles around a vehicle—even in challenging conditions like rain or fog. This capability makes radar indispensable for safe and reliable driving. How Radar Works Radar measures distance by emitting radio waves and analyzing the time it takes for the reflected signal to return. Common automotive radar frequencies include 24 GHz, 77 GHz, and 79 GHz , with 79 GHz expected to dominate due to its superior resolution. Unlike cameras or LiDAR, radar performs well in poor visibility. Cameras excel at color and shape recognition but struggle in bad weather, while LiDAR offers high-resolution 3D imaging but loses accuracy in rain or snow. Radar complements these sensors, creating a robust multi-sensor system for enhanced safety. Market Trends: Why Radar Demand Is Rising With the rise of autonomous vehicles and mandatory safety features like automatic braking, radar adoption is accelerating. Higher frequencies improve detection accuracy but also increase data processing loads, creating new challenges for electronic components. Future radar systems demand: High Power : To handle increased processing loads. Heat Resistance : Preventing performance degradation in compact designs. Compact Size &amp;amp; Lightweight : Essential for modern automotive architectures.

At the heart of this process is the On-Board Charger (OBC) — a critical system that converts AC power from charging stations into DC power suitable for vehicle batteries. In this article, we’ll explore the role of OBCs, their system architecture, and the Panasonic components that enable high-performance, compact, and reliable charging solutions. What Does an On-Board Charger (OBC) Do? An OBC is a power conversion system installed in EVs and PHEVs. It transforms AC power from residential or public charging stations into DC power required by the vehicle’s battery. Most OBCs operate in the 3.6kW to 22kW range, depending on regional standards and vehicle specifications. ⚡ Types of EV Charging ・Normal charging In normal charging, the battery is charged to full. The battery of an EV is charged with AC voltage from a private residents&amp;#39; charging equipment or a public charging station. Generally, charging the battery fully takes about eight hours. In the case of normal charging, the OBC incorporated in the vehicle converts AC voltage into DC voltage applicable to the vehicle battery. ・Quick charging Quick charging is charging to refill the battery in a short time. In quick charging, the charging station supplies DC voltage corresponding to the battery voltage, charging up the vehicle battery in a short time by quickly feeding the battery with large power. Quick charging, in general, takes about 30 minutes to 1 hour to finish, depending on the battery capacity. You will find those chargers for EVs in a lot of expressway rest areas, commercial establishments, etc. Charging Type Power Source Location OBC Usage Charging Time Purpose Normal Charging AC (200V/400V) Home, Office Converts AC to DC ~8 hours Full battery charge Fast Charging DC (direct output) Highways, Commercial Facilities Not used ~30–60 minutes Quick top-up Normal charging relies on the OBC to convert AC to DC, while fast charging bypasses the OBC by supplying DC directly to the battery. Battery Capacity &amp;amp; OBC Output Battery capacity varies by vehicle type (compact, SUV, sports car). OBC output is designed to fully charge the battery within approximately 8 hours, with regional variations in specifications. Market Trends &amp;amp; Component Requirements As EV adoption accelerates, OBCs must evolve to support: Higher output power Faster charging times Smaller battery sizes To meet these demands, electronic components must offer: High voltage tolerance Large current capacity Low power loss High heat resistance Compact design OBC System Architecture The OBC system consists of multiple circuits: Voltage Measurement (Input/Output) – Controls conversion accuracy using high-precision chip resistors. Noise Filters (Input/Output) – Suppress external and internal noise using automotive-grade film capacitors. Full-Wave Rectifier &amp;amp; PFC Circuit – Converts AC to DC and improves efficiency using capacitors and inductors. Voltage Conversion Circuit – Uses transformers and switching elements with noise-suppressing resistors. DC/DC Converter – Powers control circuits using hybrid aluminum electrolytic capacitors and power inductors. Communication Interface – Protects transceiver ICs from ESD using chip varistors.
