100K uf 25V Capacitor

[George S]

I posted a while back that I needed a 100K 25V electrolytic cap for an
Astron RS-50A Power Supply. I couldn't find one from the usual suppliers
that would fit into the power supply case.
I contacted Allied Electronics and the sales person got in touch with
Cornell Dubilier Marketing Inc. They sent me two free sample capacitors at
100K uf 25V. One of them is a perfect match for replacement. Since this
capacitor isn't a normally stocked item it was sent as a free sample.
Something to remember if you run into a replacement part problem. To try the
manufacturers when you need something a supplier can't get for you as a
single item order. I've gotten free sample resistors the same way also.

I should have posted this as a Tip for parts.
Sorry, George S

Exactly what is a "100K uF" capacitor? ;-)

Well it is an Electrolytic capacitor that looks like you should grab a beer
can opener. Punch a couple of holes in the top and have a cold one.
I wonder how many here still have a can opener like those in the kitchen or
shop any more, or the all popular "church key"???

I'd guess, 100 milli-Farads or 0.1 Farads. At 25 volts that's a heck
of a lot of Joules.

Well, 32.1 J.

I calculate 31.25 J. re: W = 0.5 CV^2
Are you turning dyslexic, Sam? ;-)

Sorry, it seems I've had a brain fart. I see now that "100K uF" is
just another legitimate way of saying 100,000uF, although to me it
sounds unusual. I guess it's a bit like expressing 1V as 1K mV.
