Re: MMC cap dissipation testing

the cap is of the ECQ-E series - I've been selling them for $20 per bag of
100 plus $5 shipping - I was told that they were originally to be used as
snubbers in some kind of inverter, but who knows??  I have a few bags left,
I plan on keeping one bag for myself, but the rest can go.
