What Is a Ceramic Capacitor?
A capacitor, also called a storage cell, secondary cell or condenser, is a passive electronic component that is capable of storing an electric charge. It is also a filter, blocking direct current (DC) and allowing alternating current (AC) to pass. A capacitor is composed of two conductive surfaces called electrodes, separated by an insulator, which is called a dielectric. Unlike some capacitors, a ceramic capacitor is not polarized, which means the two electrodes are not positive and negatively charged; and it uses layers of metal and ceramic as dielectrics.
