Hi !
 
I recently purchased some .02 MF/20KVDC rated caps for use in my coil.
I've tried a couple of them and they seem to perform well. I've only
tested the setup for very short runs, since I'm a bit concerned about
how high AC voltage they can handle.
 
There's no manufacturer info on the caps. They're labeled F-C-1.
D6-200-20, 69-18, 5910-9410310 (ceramic body, 12 cm long, 4 cm
diameter). Does anyone have any experience with these caps in a TC ?
What's the max AC voltage I can apply without worriying about seriously
reducing the lifespan of these caps ?
