Checking panasonic's electrolytics catalog came up with a 4cm x 8cm 450V 1000uF cap.  Considering the one you have is probably a lot lower quality than the panasonic, I wouldn't be surprised if it's rated for 750V or more for it to be that big.  A camera flash is going to have extremely high voltage requirements with almost no current draw, so that sounds about right.

yup./ . .im used to small capacitors too. . .so when i held that in my hand (instead of my fingers) i was like OMFG. . .im gonna kill someone ;D

Although I've used black gates before and a 50v 1000uF cap would be about that size.  The cost was also obscene.

I suppose I'm trying to be conservative here, going over your WVDC of the capacitor is dangerous (possible explosion).  Yes it could be well into the hundreds, it's hard to tell.  I highly doubt the WVDC of the capacitor is in the 1000V range and I'd put an upper bound of around 500V as it may be newer than I thought; again it's a guess.  At 1000uF that's a fair large capacitance there, usually people don't make high voltage capacitors at that capacitance.

And yes this picture was to be somewhat hilarious:

caps (it's a link to cut down on bandwidth for people who really don't want to look at round cylinders)

Most of these capacitors are really old, except for the three "tiny" ones in the front (there are many SMT caps are smaller).
(My project with these capacitors was a little less destructive than a railgun/coilgun.  I was planning to make a small welder with them.)

This is the biggest cap I have played around with:

Yes, that is a 19 inch rack

80μF, 10kV
