Ceramic capacitors, commonly referred to as "cer caps," are a type of capacitor that utilize ceramic material in their construction. They are one of the most widely used types of capacitors due to their numerous benefits, including low cost, small size, and high reliability. Ceramic capacitors typically consist of two metal plates separated by a thin layer of ceramic material, which provides excellent insulation properties. This design allows them to store electrical energy efficiently while minimizing power loss. Their ability to withstand harsh environmental conditions, such as extreme temperatures and humidity, makes them an ideal choice for various applications in electronics, including filtering, coupling, and bypassing circuits.
