supercap leakage

John Larkin · 2017-05-24T21:34:23+00:00

Looks like it would be fine to stack these in series without any equalizing parts, like regular wet aluminum caps. Measuring supercaps is an enormous pain; every step takes hours. The equivalent dielectric absorption is huge. Leakage tempco appears to be strongly negative, but that may be an illusion. -- John Larkin Highland Technology, Inc picosecond timing precision measurement jlarkin att highlandtechnology dott com

I kept increasing the voltage until I got a lot of leakage.

I think it's a very good capacitor.

And declines with a time constant of days.
