Cap is from the DC-DC PSU for a Siemens 840D computer, Mobile Pentium 2 333Mhz CPU running NT4, same as this one but an older model...
I exchanged only this one cap, the rest are Rubycon and Nichicon and look pristine, the system is about 10 years old.
They put the PSU's "startup cap" or timer cap wedged between the primaries, a couple switching diodes and a big heatsink, so not very strange that it failed eventually. (Which also made it a PITA to replace!)
System would not power on after a 4 week vacation, and before that it had problems starting up so I was pretty sure it would be this "startup cap".
And I was right, I replaced it with a Rubycon ZL 100uF 25v (closest match I had) and it booted straight up.
It's funny that a $0.02 cap can prevent a machine costing around $500000 from booting
But what bothers me is I can't identify the little bugger, has anyone got a clue what brand this is and what it's specs are?
We have 3x machines with this kind of control system so it would be nice to replace it with something that is closer to the originals next time one fails...
