Capacitor Size Farad

Standard Capacitor Values & Color Codes

The basic unit of capacitance is the Farad (F). In order to obtain other values of capacitance, it is necessary to use parallel and/or series combinations. Often, complex combinations are used in order to satisfy multiple requirements such as handling large voltages while still providing the correct amount of capacitance.
