Hi guys,

does any one know about the data's (rf current handling) of the Mica
Capacitor:

CORNELL DUBILIER, TYPE 9H
.0004 MFD (400pF),
WKDV 2500VDC
TEST 5000VDC

I'm interested how many rf current it can carry. I used four of it in
parallel with a vary cap together as C2 in the final pi-net of my  75m
amp using four of  4-1000. Two times one of these caps failures (rf
power shorts to ground). May be this capacitor is not suitable for  rf
current? Any comments?
