Re: WIMA FKP1-MMC

I've been using the 68nF/1600V Wima FKP1 caps for about 2 years now.
First in my large coil with a 4-MOT Supply at ~8 kV using 10 caps per
seem to handle the current fine, I have never noticed any heating at all,
not even when the primary made of 1/4" tubing was almost too hot to touch
after longer runs. (More than 10 minutes)
Now they are in a smaller coil, 13 caps per string on a 12 kV transformer.
