Wondering how you wire a “super capacitor” v2

There's a little bitty 3kF capacitor on Mouser for like $73.  But how would I wire it up? like this?

That will over volt a super cap and short it, you need 2 in series as they can only take 2.5 volts, 2.7-2.8 max. With super capacitors you get fooled by the big rating. The values of the super cap are rated by capacitance reactance in a certain moment, not energy capacity. Even though there is a significant increase in energy density, its not directly proportional.

And yours most likely has a low amperage rating if it's really small

Interesting. I'll have to use wikipedia to decode some of that.

Seems to me some of them (at least) can go to very high Amps: http://goo.gl/NEx3Jm ← data sheet for a beast
