How many ufa of condenser is good for 12V ignition coil?

For a 12V ignition coil, a typical value for a condenser (or capacitor) is around 0.22 to 0.47 microfarads (uF). This range helps to suppress electrical noise and improve the performance of the ignition system. It's important to use a capacitor rated for at least 25V to ensure reliability and safety. Always consult the specific ignition system's requirements for the best results.
