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
Gaz.

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

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 :eyebrows:

Your gonna love this, please clean you Caiman quickly :)

Lots of lovely electrolyte from newly leaking caps :doh:

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

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)

http://cgi.ebay.co.uk/16V-10000uF-10...item19ba9ad704

"lead spacing 10mm..."

Ah, snap in with 10mm spacing :scratch:

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. :cool:
