It says film, so if it's polyester/mylar it will probably heat up on even
100-200 watt coils, pushing your luck with higher power. Personally I never
use anything with a tall bushing in a TC tank just to be safe. After seeing
a cap split its side and spew flaming oil like a mini flame thrower  for a
couple seconds (used a string of caps from MO's, luckily it was outside and
didn't explode per se with shrapnel), I never use unknown or questionable
caps in TC's or any other pulse duty. Any other people out there have any
similar cap mishaps?
