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.

It seems like AI isn't AI-ing - just spewing random snippets of a user manual.

I feel like I joined a conversation here well after it started.

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.

Perhaps sometimes it fails to fail at all.

Looks like a copy from here:

https://industrial.panasonic.com/ww/faq/faq0003

However that in itself was originally a bad answer too, because anyone asking that would want more detailed information than, to paraphrase, "open circuit but sometimes short".

This is a very pointless blog.. are you saying that the documentation should be checked regarding some random product that you do not mention?

RE: 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?

shabaz — Mon, 10 Nov 2025 03:51:14 GMT

Hi,

This is a very short blog post, and leaves readers feeling wanting more perhaps. It might be more valuable to readers to have many things discussed in a single blog, rather than multiple one-sentence blogs.

Wurth do excellent blogs for comparison, here's a Wurth blog on one type of capacitor:

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.

RE: Laser sensor for measuring velocity of very fast moving projectile

shabaz — Sat, 18 Jun 2022 20:43:37 GMT

5-20 usec is not a very short time, wouldn't any small photodiode operate in that range? I don't think it needs to be very specialist.

Alignment might be awkward. I've no idea how that's done in commercial systems, but there's probably plenty of information google'able, since it's not a novel thing.

If alignment is not easy I can think of other photographic techniques to determine the speed - for instance a CCD system and two brief (nsec) laser pulses to illuminate it twice at a fixed time period. That's quite advanced, would require a very well equipped lab.

RE: Panasonic Capacitor 1000uf, 200V, failure concern

Panasonic Capacitor 1000uf, 200V, failure concern

Former Member — 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

Hello Hiroshi,

I have these Panasonic capacitors that have been bulging from the top. Could you help tell me if these are counterfeit or legitimate Panasonic capacitors? Any help would be great. Thanks.

RE: Ask me questions about Sensors

roz — Fri, 14 Oct 2016 14:09:26 GMT

We have a question about Sensors.

Our 11 year old boys are assembling a table top basketball court and would like sensors on the floor of the court to determine the distance of a shot, as well as a sensor near the basket to tally the score whether it be a 2 or three point shot. There will not be players. As stated, they are assembling a table top sized court approximately 2 feet by 12 inches. There will be a ball that springs towards the basket. The sensors will have to sense the distance of the shot on the court and determine whether it was a 2 or 3 point shot. A sensor near the basket will tally the score. The facts are we don't know what kind of sensors we would need to purchase for the boys to program in order to execute. Could you assist in the appropriate direction with the type of sensors needed and an app that would assist with this project? Any help would be greatly appreciate.

Thanks!

Do you have questions about pressure, motion, passive infrared and light sensors? Please ask me.

Jane Awittor last logged in to E14 in October 2012 - I doubt that she will answer you.

I suggest you re-post this question in a different place and with a lot more explanation, diagrams and pictures help.

350cc is a very small tank - how does it's volume change - what is it made of and what is in it.

RE: Ask me questions about Sensors

Former Member — Mon, 22 Jun 2015 05:28:23 GMT

Hieee jane

I wanted to knw if there are any sensors tht could detect the change in volume in a tank when the tanks is in motion and when it is in some bumpy regions and hill regions like sensors jonit in line at transmitter and receiver and volume of tank is 350cc

RE: Ask me a question about Solid State Relays?

Former Member — Tue, 17 Mar 2015 14:59:46 GMT

Hi Aiman,

I am working on project to control a temperature of a coolant system so basically I am using PID temperature controller to drive 2 solid state relay to switch my loads on/off, the SSR drive in my PID controller Max current rate is 20mA, let assume that the 2 SSR required more current, could you help me to find external SSR Driver circuit that boost the current from my SSR driver in my PID controller and this external SSR drive will drive my 2 SSR ( like if you give me a product name so I could purchase it) waiting for your reply with many thanks.

Dear Justin,

You will proberbly need a level shifter. Please check the bandwith of your design. How quick your signal has to be?

Could you please give me more info on it.

Cheers,

Simone
