Hank,
Look at TDK CC45 capacitors. Available at Mouser with number
810-CC45xxxxxxxx. They are about $.15 in 1k quantities. The data sheet
specifically says "low dissipation at high frequency". They are rate at
6kVDC. I have tried*unsuccessfully* to blow them up at HF with no DC
and RF voltages of 2kVpk. However the ones I was testing were 10pF,
22pF, and 47pF so the current would be much lower than the higher
capacitance ones.
