Well, I'm not sure that the Maxwell's I'm getting are the ideal type for
Tesla Coil use, but they're all I could get my hands on. They look like the
type "SP" shown on this site: http://www.surplussales-dot-com/Maxwell.html
The Maxwell part numbers are: 37218, 31507, 31677 and 31393, but I don't
have access to the datasheets. Except for the 31393, these are no longer
listed on Maxwell's site as best I can tell. The voltage ratings are just
40kV, AC or DC is not specified. The current ratings are 25kA pulse, 25A
rms, but these are all at 20% "voltage reversal".
If someone could explain the definition of the voltage reversal percentage
to me, it would be quite helpful. Do they they mean the peak-to-peak
voltage divided by the rated voltage?
