Seems the choice isn't all that critical, but as I dont have any caps lying around I'd need to order one in anyway..might as well get something good?

Thanks.

I'd suggest just about any that are over 20V DC rating & have the same leg spacing. Failing that look for a Panasonic FC that'll fit, these are also good for PSU rails

If you can find the distance between the capacitor legs & let me know, i'll have a hunt about for you

hey...thanks Mark!
I'll see if I can find out.

Cheers

Pull the buggered one out & get a ruler against the legs. Trust me it's well & truly stuffed

**Gazjam** · 23-05-2011, 17:55

ok dokie...

Not got a soldering iron though, use the old mans tommorow.

Thanks Mark.

Hey Gaz, just remembered i happened to have an electrolyte damaged 500W SMPS PCB, so went looking & i found it

Your gonna love this, please clean you Caiman quickly

Lots of lovely electrolyte from newly leaking caps

Given a bit of time... This was a section outputting +/- 15V DC, same as your Caiman input

There is a hole where a capacitor used to be, you can see the charring plain as day, the fibreglass PCB has absorbed the electrolyte & started conducting current, from then on it's a slippery slope to oblivion!

Get it cleaned ASAP m8, not pretty is it

You plonker Rodney

Meter it before you plug it in

Maplin sell IPA

Not cheap though.

Google shopping results:

I could post you a can tomorrow, I have lots of it

Wear latex gloves when working with leaky capacitors and IPA etc,

Hey Mark,
Was given this link by Stan.B. (thanks Stan)

"lead spacing 10mm..."

**Reid Malenfant** · 23-05-2011, 21:27

Ah, snap in with 10mm spacing

You could use a cap with less spacing & have it a tad above the PCB if needs be, just as long as it actually fits in the limited height.

Cheers, gives me more idea what to look for

Thank you Mark.

Gaz.
