Ceramic capacitors are a type of capacitor that uses ceramic materials as its dielectric, typically in the form of a ceramic disc or plate, to store electrical energy. They have various applications across different industries, including electronic circuits and devices. This component is often used for decoupling and filtering purposes due to its compact size and stability under varying temperature conditions. Ceramic capacitors are also known for their relatively low cost compared to other types of capacitors, making them a popular choice in many designs.
