How Long Do Capacitors Hold a Charge?
When it comes to how long a capacitor holds a charge, the main factor is its capacitance value—the higher the capacitance value of a capacitor, the longer it can hold and store electrical energy. A typical capacitor has a capacitance rating ranging from 1 microfarad (µF) up to thousands or even millions of farads (F).
