Audio rated caps - is it ok to use ‘audio’ rated caps on a non audio device

[Phil289]

Hi
Just a quick question - is it ok to use ‘audio' rated caps on a non audio device.
Is there any reasons why they shouldn't be used?
I'm just trying to find some good quality caps on ebay for a small repair and I've noticed there are alot of audo rated caps in the size i need but not so many non audio rated.
If I can't find any Panasonic what would be any other good makes to consider?
Thanks 🙂

22uf 35v and 100uf 35v
the thread you posted used the wrong caps - you need long life high temperature ones - not 2000hour 85' crap.

if your buying from RS then you may be able to get 125' caps - i'll check later

I've opened mine up and took photos
KME on the 22uf
The silver one 100uf 16v is not like anything I've seen before so it looks like something a bit special - it has a black line down one side, is that the neg?
Thanks for your help 🙂

"Audio" caps are a rip off, 85°C rated and short life in the 1,000hr league. But they have silk inside lol.

OP it's for automotive use, under the hood? Get AEC-Q100 etc. certified parts and consider the 125°C rated if you live somewhere hot. Don't waste your time with mediocre parts. Polymers would be great here - unless the caps are timing something and the 22uF part looks like that so you need low leakage.
The webpage the guy used Radio Shack/Xicon only reated to 85°C 2,000hr parts and guess whose going to have to replace them again. Under the hood is very hard on parts.

I found this cap on rs components - i know its the wrong rating but do you think it could be the same series as my silver 16v 100uf ?
It certainly has the same type of writing on it .

I hadn't realised they were quite low spec - i just worked on the assumption that they had been working for 20 years and so another 20 would be just great 😊
Its hard to know exactly whats good and what's not as there's so many different makes and series it gets quite confusing - plus with all the fakes about its all a bit of a gamble if your limited to where you can buy from.
Would be nice to just walk in somewhere a buy over the counter but there's nothing local to be able to do that.
Thanks for the help I really appreciate it 👍
