automotive ignition condenser uf and voltage rating?

    Anyone know an approximate rating for an ignition condenser like
    voltage and uf? Can these things be used in HV electronics as a
    regular capacitor?

    0.33uF 200V? Ballpark.

    Replace with a snubber rated film capacitor, encapsulated further if
    necessary (considering most points caps are metal cased!).

    If you're asking if you can use some in a different circuit, sure, but hell
    I don't know why you'd be asking the value, it's usually stamped on the
    things you know.

    The "condenser" I tested read 0.2 uF.
    As for voltage rating, I'd guess several hundred volts. Traditional
    from old style, dwell based inductive ignitions have a turns ratio of
    about 100 to 1. If such a coil puts out about 20kV, that means the
    condenser would have to withstand 200 volts, but of course it must have
    a significant safety margin -- maybe a factor of two? And then there
    "coil fault;" if a spark pug wire falls off and there is no place for
    the coil's
    energy to go, the flyback voltage is even greater. I would think a
    would have a 400 volt rating, ballpark, but that is just semi-informed
    on my part.

    Thanks, that helped.
