What are the storage requirements?

riyo@panasonic — Mon, 10 Nov 2025 02:49:55 GMT

Check the details of "Storage" included in the product safety precautions.

What is its failure mode?

riyo@panasonic — Mon, 10 Nov 2025 02:48:44 GMT

For normal operations, it’s basically in open mode. However, please note that a short (an increase in current leakage) can occur when it is used under severe conditions. Please check the Safety Precautions first.

In the case where voltage is applied to a hybrid capacitor, does the hybrid capacitor show the same bias characteristics as a multi-layer ceramic capacitor (MLCC) does?

riyo@panasonic — Mon, 10 Nov 2025 02:47:18 GMT

The hybrid capacitor keeps its capacitance unchanged when a DC bias voltage is applied, while the MLCC has its capacitance changed by the input DC bias voltage.

What is the difference between conductive polymer hybrid aluminium electrolytic capacitors and ceramic capacitors?

riyo@panasonic — Mon, 10 Nov 2025 02:34:53 GMT

Conductive polymer hybrid aluminium electrolytic capacitors, or commonly known as hybrid capacitors, are categorized as electrolytic capacitors. They differ from ceramic capacitors in terms of structure, material, and basic principle. These capacitors are superior to ceramic capacitors in the following aspects: (1) large capacity, (2) stable temperature characteristics *1, (3) no need to take bias characteristics into consideration *1, and (4) no need for sound prevention measures *1. (*1: Ceramic capacitors exhibit inherent disadvantages)

Laser sensor for measuring velocity of very fast moving projectile

Gasgunguy — Sat, 18 Jun 2022 04:50:42 GMT

I am looking for laser sensor to measure velocity of fast moving bullet/projectile traveling through barrel.

I have a bullet of 5mm length and it would cut the laser for just 5- 20 microseconds. The sensor need to be fast enough to give trigger to oscilloscope with this kind of small intervals disturbance.

I am looking for suggestions on possible sensors for this kind of measurement to be possible.

Bullet details: 5mm dia , 5mm length , can move in velocity 10m/s to 1000m/s.

Panasonic Smaller and High Power CSP Schottky Barrier Diode

e14 Contributor — Thu, 29 Aug 2013 12:17:27 GMT

Pansonic has launched Industry Smallest (*1) CSP type Schottky Barrier Diodes

with key characteristics, such as Ultra Small Packaging, High Power and High Heat Dissipation, and Higher Efficiency

with less Voltage Loss, suitable for Power Circuits in Mobile applications.

As electronics products continue to go smaller, thinner and lighter,

board sizes also have the same size limitations, resulting in extremely dense circuit designs.

Therefore, downsizing all components are a must and thermal management has become an even more important factor in board designs.

Also, despite the limited space, the power supply circuit has even more loads with constantly growing data-communications

and High-end High-tech functions.

To solve these issues, Panasonic is announcing a new CSP Diode series, with features such as Ultra-small packaging. (0.6mm x 0.3mm), Industry top-level Low Forward Voltage (15% reduction), and Industry top-level thermal performance (33% heat reduction) .

This series has a line-up of 16 parts to fit all customer designs and requirements.

Panasonic Power Mount CSP MOS FET

New Power CSP (PMCP) MOSFET
High thermal yet the smallest size utilizing new package technology

Panasonic Semiconductor has developed the New Power CSP MOSFET

This MOSFET family is optimized for load switches that combine low RDS(on) in a smaller form factor,

reducing the power management system size and minimizing power consumption to increase power efficiency.

Features

- Panasonic’s unique Power Mount CSP package allows for improved thermal dissipation by 5% while reducing the size by 80%

over the conventional solutions.

- Employing a fine trench silicon technology that provides 47% lower RDS(on) over the same sized conventional chip.

By using this technology, this MOSFET family achieves higher power efficiency while reducing power consumption of the system.

New technology

- Adopting a new heat discharging frame structure

PMCP utilizes the new package structure of unique pad design and drain clip technology,

which achieves higher thermal performance over the current products.

Our thermal design utilizes a frame structure to optimize thermal dissipation from the chip to both the PCB and air;

a higher thermal dissipation over our conventional product has been achieved while achieving small size and low-profile.

- 110nm fine trench cell with wafer thinning fabrication technology

Panasonic’s advances in cell technology and wafer thinning fabrication have lead to silicon with lower specific on resistance.

Normally, in an N-ch power MOSFET, current flows from the substrate to the channel.

Increasing the number of cells by using a 110nm fine process technology reduces the resistance of the channel.

In addition, using wafer thinning technology reduces the resistance of the substrate.

Panasonic Capacitor 1000uf, 200V, failure concern

e14 Contributor — Wed, 06 Apr 2011 13:43:50 GMT

Hi,

I am at a manufacturer that has experienced failures on the rectifier board with the capacitor venting or bulging. There are three issues. Is the issue a likely failure, Is this real or fake panasonic part, have other failures been reported ?

1. We found the damaged part is a 1000 uf, 200 volt, capacitor part EETED2D102CAEETED2D102CA with a date code of 0921 (M). Our analysis was that the capacitor has corrosion on the leads which causes the capacitor to fail then the imbalanced capacitors on the rectifier board causes a voltage spike that ruins the electronics. Is it possible or a likely root cause to have corrosion on a lead ?

2. I attached a photo. Is the 0921 (M) code a real panasonic part date code and if so what does it mean. We are finding other panasonic 1000uf, 200V capacitors that are slightly different in height and diameter and plastic cover print font.

3. Are there any other field reports of problems on this capacitor.

Thanks
