There is more to it than just the voltage as Tom explains.
I bought some .1mf that were 1000 volts for the Super Elto
ignition. Testing I could get a spark but the motor wouldn’t
run. I guess they were too slow as Tom describes.
Let us know how it works out.
There’s one more specification for a condenser, that’s the dV/dT, or how fast the component and move the voltage. To function in a magneto circuit, the value has to be pretty high, a lot higher than most uses. I think if you search this site a bit more, you can find a little more information on which ones have worked well in magneto applications. (Try “MKP 1839”.) I don’t know what the markings on the one shown above mean, so I can’t rule it out. The Vishay MKP 1839 HQ series should be OK.
