A capacitor is a device that stores electric charge in an electric field. It is a passive electronic component with two terminals. Made of ceramic material as the dielectric and metal as the electrodes, ceramic capacitors come in a variety of shapes and sizes. They are generally less expensive than other capacitors and carry lower capacitances (couple of µF max.), which makes them used often during low capacitance requirements in noise/harmonics filtering and suppression applications. Multiple ceramic layers may also be arranged and compressed together to form a block, reducing equivalent series inductance and creating a monolithic ceramic capacitor.
