I'm trying to estimate the power losses in a voltage multiplier built with cheap ebay ceramic capacitors (which I believe are designated as Y5U).
Unfortunately, the only spec I've been able to find on dissipation factor is < 2.5% @ 1.0 kHz. But what is it at 10 kHz or 20 kHz? Does anyone have any info on this?

the y5u's vary wildly with temp but z5u's are even worse.
let me look in my special books....brb
EDIT: nope cant find it, too drunk...
