Ceramic Capacitors are a type of passive component used in electronic circuits to store electrical energy. They are commonly referred to as CAP CER, an abbreviation that stands for Ceramic Capacitor. These capacitors utilize ceramic materials to provide a stable and consistent capacitance value. Their compact size, reliability, and low cost make them widely used in various applications, including filters, resonant circuits, and power supplies. The specific characteristics of ceramic capacitors vary depending on the type of ceramic material used and other factors, but they generally offer a good balance between performance and price.
