AI Customer ServiceAlmost all automotive distributor coils use a 0.25-0.29 microfarad capacitor. The operating voltage rating should be no less than 600 volts DC. There are now capacitors available in the 0.25 microfarad range rated at 630 volts AC.
The operating voltage rating should be no less than 600 volts DC. There are now capacitors available in the 0.25 microfarad range rated at 630 volts AC. Since the AC peak voltage is 1.4 times the nominal value these capacitors are actually 880 volt DC capacitors making them ideal for ignition use.
Capacitors bearing “High voltage” and/or proprietary anti-arc designations are designed for use at application voltages beyond that which is typical for electronic devices. Definitions of what constitutes “high voltage” vary between manufacturers, though the lines of demarcation seem to fall in the 100 V to 1 kV range.
Capacitors have the ability to store an electrical charge in the form of a voltage across themselves even when there is no circuit current flowing, giving them a sort of memory with large electrolytic type reservoir capacitors found in television sets, photo flashes and capacitor banks potentially storing a lethal charge.
Eugene My experience is that that capacity of both magneto and spark coil capacitors range from 0.2 microfarad to 0.33 microfarads. Almost all automotive distributor coils use a 0.25-0.29 microfarad capacitor. The operating voltage rating should be no less than 600 volts DC.
The Working Voltage is another important capacitor characteristic that defines the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Generally, the working voltage printed onto the side of a capacitors body refers to its DC working voltage, (WVDC).
