Heya,
I just found bags of electrolytic caps in my basement storage from 1990's. Mostly 1000uF and 470uF. close to 1000 total.
I think I bought them from Jamco back then. A bag of a 1000 a piece.
They test fine on 2 component testers I have and show an ESR of only 0.050 Ohms!
I went to measure them for leakage with my DMM. On Ohms setting, I read 4 Meg Ohms for 1000uF and 40 Meg Ohms for 470uF!

Aren't these caps supposed to have high enough resistance, that they shouldn't register with regular DMMs? My DMM croaks after 60 Meg Ohms and shows Over Range.
Are these caps good now after 25+ years. Would caps from 90's be considered old and leaky?
Just wondering if they're worth hanging on to...?!
Cheers.
