The MMC type caps work good on small and medium size SSTCs and also 
SGTCs. These are typical coils powered by nsts (the SGTC type).

Usually at power levels above 6-7 kVA, where the peak pri currents 
exceed 2,300 to 2,500 Amps, one makes the transition to commercial 
grade pulse duty caps rated 60 kV, typically at 0.05 to 0.2 uF 
range.   We use 0.06 uF (60 nF) in the 6-8 kVA range, and 0.1 uF (100 
nF) in the 10-15 kVA range.  I go to 0.2 uF above 15 kVA and around 
0.3 uF at 25 kVA.
