Ceramic capacitors are a type of capacitor that utilize ceramic as the dielectric material in their construction. They are widely used due to their relatively low cost, small size, and ability to be made with a high degree of precision. Typically, ceramic capacitors have a lower capacitance value compared to other types of capacitors but offer higher stability over temperature changes. They are commonly found in various electronic devices such as filters, resonant circuits, and power supplies due to their capacity to store electrical energy efficiently.
