Elna caps for power supplies?

Re: Elna caps for power supplies?

Are you absolutely sure it wasn't the way the transistor blew a hole in itself while also flaming the nearby capacitor? Cause if the cap blowed, it would be either from top or bottom, never side. Side is made from not-that-thin aluminium in a shape of can.

The cap may actuall be fine, you'll just need to strap some tape around it to isolate the can.

I wasn't sitting there watching it happen, so it is all guesswork, really. It seems pretty odd that either one of these things managed to blow a hole in the other!

Maybe because the cap is bigger and it has a bigger hole in it, I jumped to the wrong conclusion. Here are some pics of the chip.

But uh... I don't think I would use that cap again unless I was in a real pinch! Taped or not!

It probably has dual 12V rails. One 2200uF 16V cap for each rail and maybe even an inductor for each rail too.

Maybe. The dual rail concept may not have been popularized yet, though. I bought that PS in 2003. I don't remember it being sold with claims like that.

I think it is the transistor that blew out first. I've known them to melt pits in heatsinks before when they blow out. I don't think it would have too much trouble melting the thinner aluminium of a capacitor.

We have gotten off the original topic here, so I will go back and try to rephrase my question...

If Samxon caps are OK and superior to CapXon, Fuhhjyu, etc. just where can I get some to put in my PS? I mean, I need a 3300uF 16V 10mm cap and this site no longer stocks anything like that and I CANNOT find anyone else selling SamXon. Are they still in business?

Behemot on this forum (look a few posts above) placed a custom order at Samxon for them and has 10mm capacitors

He sells them at a fair price too. They've come in handy for me on some projects

Oh man that's cool being marketed by other ppl, that's the sign you are making it good

Anyway, here's the list.

Thanks! I don't see a language dropdown on that site and I don't know the language. How are the shipping charges to US? And what is the exchange rate?
