[Amps] current handling capacity of SM caps

[Jeff Blaine]

Any idea of what the current handling capacity would be of the generic silver mica 500V cap?

Due to the intervention of Murphy, I may be pressed into using a few of these paralleled in a L/C match for an antenna feed for this weekend’s WPX RTTY contest.  I don’t have time to find doorknobs because I’m about a day or so from knowing what the correct values are going to be.  but I do have a pretty big junkbox of SM units in a big spread of values.

I was hoping someone would have a feeling as to the current carrying capacity.   Applied power will be around 1300W at 7 Mhz.  Xs will be in the 10-25 ohm range (so 2200-1000 pf).  Which I think means peak currents of as much as 12A total...    Ugg
