There's no real power in a Var since Vars = V*I*sin(A).

I should have said a rule of thumb. A 1kvar capacitor should be good
for a kilowatt amplifier. I believe KVAR, RF current and RF voltage to
be a complex matter. Maybe someone really smart could write a program
that could work out what the TRUE RF current rating of a capacitor is
versus frequency and its KVAR rating, now that would be useful.
