The capacitors impress with their vibration resistance in accordance with IEC 60068 2-6/2-27, their very long service life, a safe failure mode and their power stability. The capacitors achieve the highest safety standard by using epoxy-impregnated paper as a dielectric. In addition, excellent self-healing properties minimize the risk of short circuits, and the use of advanced materials also ensures maximum tightness and therefore particular stability against ionization, corona effect, and partial discharge. Surface Mount Technology (SMT) enables reduced assembly time, saves space on the PCB and reduces parasitic effects typical of Through-Hole Technology (THT). The capacitors are lead-free and RoHS-compliant, as well as THB-tested and AEC-Q200-certified. This makes them ideal for applications in the automotive sector, such as in infotainment and comfort equipment or safety systems, but they are also ideal for use in the medical and industrial sectors.

Considering it only takes a few minutes to replenish the current internal combustion engine, many EV systems are looking for better, faster ways to get back on the road. Currently many EV systems use what is called an On-Board Charger to replenish the battery. This kind of system is preferred, as it takes in readily available AC power from the grid and convert it into DC power for the battery. Considerations about it&amp;#39;s size, weight, energy efficiency, and cost all need to be taken into consideration when designing the On-Board Charger (OBC). There are four stages in a OBC; EMI Filter/Input Stage, Power Factor Correction Stage, DC-DC Conversion Stage, and Output Filtering Stage. Throughout this article we will discuss the various stages and what components are in each stage. Shown above is the architecture for a basic OBC that is supplied by 3-Phase AC power. Similar versions of this architecture would be used in a single phase application. Using this 3 phase architecture allows for a rapid charging period and higher efficiencies. {tabbedtable}City Information EMI Filter The first stage of the OBC is the EMI filter. During this stage AC power is filtered to remove any unwanted noise from the typical AC sine wave that is expected. This noise is caused by a wide variety of different things including electric motors, cellular networks, transformers, and other variables traveling throughout the grid. In order to protect the other OBC stages, the EMI filter limits voltage and current spikes that can be harmful. Most commonly these filters are made up of X &amp;amp; Y Safety Capacitors, Common Mode Chokes, &amp;amp; AC Harmonic Filter Capacitors. Many household devices contain EMI filters internally similar to this design (typically single-phase variations) in order to protect the components and the user. Shown in the figure below is the waveform before and after the EMI Filter. This can reduce the amount of filtering needed in further stages. Power Factor Correction The second stage of the OBC is the Power Factor Correction Stage. Power Factor is a calculated ratio comparing the power input to the device to the power output from the device. This is an important value in terms of efficiency, however it also can cause issues to the grid, components, and user if not done properly. Poor power factor can be caused by two things, displacement or distortion. In each case, the voltage and current values must be adjusted in order to maximize the operating power of the circuit. This can be done actively or passively. Displacement occurs when the circuits voltage and current sine waves are out of phase of one another. Another way to look at this would be to look at the power equation P=IV . If the peak voltage value is not at the peak current value in time, then the circuit is not achieving the maximum power it could. The graphs below demonstrate the differences in peak power when voltage and current are out of phase. Distortion on the other hand is described as changes in the waveforms original shape. This is often caused by non-linear circuits, rectifiers, etc. In order to correct both of these losses, a Power Factor Correction stage must be implemented. Both active and passive methods can be used. In the case of the shown circuit, switches convert the incoming waveform into a DC waveform. In order to smooth the switching behaviors of the device, both capacitors and inductors are used in conjunction of one another to buffer the abrupt switching pattern. Shown below is an example waveform outputted by the switching performance of the PFC stage (waveform shown in red). To create a smoother signal, passive components are used to create the black waveform. Once completed this stage creates a ripple voltage that can be filtered out in a later, more refined stage. DC to DC Converter In the DC-DC Converter stage, input DC power comes in from the Power Factor Correction Stage and then is stepped up or down depending on the battery system that will be implemented. In the case of most EVs, this voltage is stepped into the range of 400-1000 VDC. The step up/down voltage occurs at the transformer in the center of the circuit. The surrounding active devices work in conjunction to perform more power factor corrections caused by the transformer. Output Filter In the fourth and final stage of the OBC, an output filter is placed on the end of the stages in order to finely filter out any remaining harmonics. This is down with a simple RLC circuit in a passive context. Then the newly adjusted power charges the battery of the device, in our case a battery in an electric vehicle. Specific components are used to handle the extreme power conditions that occur in an electric vehicle output filter. Special power resistors, high voltage capacitors, and high power inductors are designed to be able to not only withstand the electrical characteristics, but the physical characteristics required in vehicle operation. Vibration resistance, temperature and humidity requirements, and space constraints are just a few of the characteristics engineers use to select components on an OBC. Uniquely, YAGEO Group offers the entire portfolio of passive components required in designing an on-board charger. Listed below are products designed specifically for each stage of the OBC.

OK, let us explain. KEMET’s dielectric offerings are expansive with different variations of ceramic, tantalum, film and aluminum-based capacitors. In addition to these varieties, we also offer multiple product grades to fit your needs: commercial, automotive, commercial-off-the-shelf (COTS), military, space and custom. Many people are familiar with most of these classifications but there is still some confusion on what exactly a COTS classification represents. What are COTS parts? For certain applications, you may want a higher reliability part that exceeds the performance and reliability characteristics of our standard commercial parts. Auto-graded parts offer capacitors certified to the AEC-Q200 standard but does not offer the ability to have parts “up-screened”. Military and space grade parts are certified to various military standards and considered more reliable but come at a premium price. With failure rated designs, additional screening options and a more affordable price, our commercial-off-the-shelf, or COTS, parts offer a happy medium. The COTS option is available for both ceramic and tantalum-based dielectrics. These part series are produced with the same materials sets and manufacturing processes as our commercial and automotive-grade parts. A series of tests and inspections are used to provide accelerated conditioning and 100% screening to eliminate failures. Each series of parts also has additional screening and conditioning options unique to that series to improve reliability and performance. Ceramic COTS KEMET has been manufacturing and selling ceramic capacitors for decades and has been continuously expanding its portfolio: more dielectrics, higher capacitance, etc. Wth the introduction of the COTS products, we have been able to further expand the product portfolio to better fit your needs. We currently offer our COTS products in the X7R and C0G dielectrics with three distinct series: standard COTS, high-voltage industrial and high-voltage military-equivalent. All parts are designed and tested to a military standard or DLA drawing with a maximum PDA of 8%. All COTS testing includes voltage conditioning and post-electrical testing per MIL-PRF-55681. Tantalum COTS for higher capacitance requirements, polymer capacitors are an excellent fit due to their volumetric efficiency. KEMET offers both tantalum with a MnO2 cathode and with our conductive polymer technology, which among other things offers longer operational life and high ripple current capabilities. These parts come with a multitude of packaging options varying from termination style (standard, facedown, etc.), construction (standard, multiple anode, etc.) and termination materials (tin, tin-lead, gold, etc.) to fit your needs. Like their ceramic counterparts, these parts are all spec’d to a DLA drawing or military standard. They are also tested to meet a specific failure rate that you select and can have additional surge current testing performed per MIL-PRF-55365. KEMET also has two exclusive patented testing options available for select KEMET COTS tantalum capacitors to improve reliability and performance: F-Tech and Simulated Breakdown Screening (SBDS). F-Tech is a manufacturing process that eliminates hidden defects in the tantalum dielectric by minimizing oxygen and carbon content in the anode, providing a stronger mechanical connection between anode and lead wire and significantly enhancing capacitor robustness. SBDS provides additional dielectric testing by identifying hidden defects. This is done through a nondestructive technique to simulate the breakdown voltage. These two tests, while at an additional cost, helps create a robust part that minimizes risk of failure. Conclusion More and more applications are requiring high reliability parts to minimize instances of failures.</description><category domain="https://community.element14.com/products/manufacturers/kemet/tags/polymer%2bcapacitors">polymer capacitors</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/tantalum_5F00_capacitors">tantalum_capacitors</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/cots">cots</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/accelerated%2btesting">accelerated testing</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/commercial%2bgrade">commercial grade</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/tantalum">tantalum</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/industrial%2bgrade">industrial grade</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/Polymer%2bAluminum">Polymer Aluminum</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/Tantalum%2bCapacitors">Tantalum Capacitors</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/ceramic%2balternative">ceramic alternative</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/ceramic%2bcapacitors">ceramic capacitors</category><category domain="https://community.element14.com/products/manufacturers/kemet/tags/mlcc%2bshortage">mlcc shortage</category></item><item><title>Wiki Page: Polymer Capacitors for Automotive applications</title><link>https://community.element14.com/products/manufacturers/kemet/w/documents/1029/polymer-capacitors-for-automotive-applications</link><pubDate>Wed, 06 Oct 2021 20:42:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:a915b14c-e9c9-4753-8420-09fc86fddadf</guid><dc:creator>Former Member</dc:creator><description>Ultra Low ESR, High Capacitance retention and AEC-Q200 qualified KEMET introduced its T598 High Humidity/High Temperature Series, the first polymer electrolytic capacitor that meets all of the requirements of the Automotive Electronics Council&amp;#39;s AEC-Q200 specification for passive components. Building on the success of the T591 Series, KEMET further refined the design, materials and manufacturing to ensure the T598 Series delivers higher stability and endurance under harsh conditions. These improvements result in a design that exceeds the humidity bias testing requirements of 85 degrees Celsius with 85% relative humidity in addition to delivering stable electrical performance at 125 degrees Celsius. &amp;quot;In 1999, KO-CAP offered engineers a breakthrough in high capacitance, low ESR and long lifetime capacitors, since this time, designers have utilized polymer electrolytic capacitors in space-constrained or high performance applications. Now that KO-CAPs meet all of the AEC-Q200 requirements, engineers can incorporate these innovative capacitors into automotive and other harsh environment applications. The T598 Series is available today in capacitances of up to 330 microfarads and rated voltages up to 16 volts. The qualification test plan is in accordance with AEC-Q200 and these products are manufactured in an ISO TS 16949 certified facility. This series is available for Production Part Approval Process (PPAP), Part Submission Warrant (PSW) and Change Control Notification.

Still not evident to every engineer, the passive component, as we know, is usually one of the last concerns. But, spending some time about “what’s different”, engineers are understanding that this new technology offers new possibilities of Ripple Capability (2 to 3 times Higher than Standard Tantalums), higher capacitance in a frequency range above 100kHz and opens the possibility for new derating rules. These arguments may represent a lower cost of ownership and enable an effective downsizing of the case sizes used and board space. Until today, when a customer was looking for an ultra-low ESR solution with a certain grading level, wouldn’t see polymer capacitors as a possible choice. These capacitors were not suitable to apply the existing MIL-PRF-55365 Weibull Failure Rate Estimates. The model would require extended testing hours in order to get the first parts failing, so, not applicable. KEMET developed one method that makes possible to grade the capacitors. The purpose of this post is to briefly describe the method employed to assess lot reliability for KEMET’s T540 and T541 Series. The objective of this method is to assess reliability levels corresponding to 0.1 Percent Per 1,000 Hours, 0.01 Percent Per 1,000 Hours and 0.001 Percent Per 1,000 Hours. The essence of the method is to test a significant representative sample of each manufacturing lot ordered with this feature under accelerated voltage and/or temperature conditions to obtain the necessary unit hours with an Accept/Reject (A/R) Number of 1/2 to demonstrate the claimed reliability level. The acceleration factors are predetermined for each design based on testing conducted under multiple conditions of temperature and voltage. The assessed reliability is equivalent to steady state operation at +85&amp;#176;C and full rated voltage as are the MIL-PRF-55365 Weibull Failure Rate Estimates. The procedure is as follows: Randomly select sample of predetermined size (at least 100 capacitors). Mount components with an additional reflow (two (2) total reflows) to test boards using conditions per IPC/J-STD-020D that are consistent with the capacitor terminal finish. Life test components using pre-determined conditions of time, temperature and voltage. Count failures at the end of the test to demonstrate that the desired reliability level is achieved based on the A/R of 1/2. This feature is an option already available in the T540 and T541 Series. To order with a B, C or D Level, please consider the ordering info in the product catalog.
