Ceramic capacitors are a type of capacitor that utilize ceramic as the dielectric material, typically made from ceramic materials such as alumina (Al2O3), zirconia (ZrO2), or titanate. They are known for their excellent temperature stability and wide range of capacitance values. They are widely used in various electronic devices due to their advantages over other types of capacitors. The low cost, small size, and high reliability make ceramic capacitors a popular choice for many applications.
