Ceramic Capacitor (CAP CER) is a type of passive component used in electronic circuits to store electrical energy. It consists of two metal electrodes separated by a ceramic insulating material, which provides the necessary capacitance. The CAP CER is commonly used for decoupling and filtering applications due to its high frequency stability and ability to withstand large voltage swings. Its compact size and reliability make it an essential component in various electronic devices, including radios, computers, and telecommunication equipment.
