Ceramic capacitors, abbreviated as CAP CER in some contexts, are a type of capacitor that utilize ceramic materials to store electrical charge. They are commonly employed in electronic circuits due to their compact size, reliability, and cost-effectiveness. The primary component of these capacitors is a ceramic material, often barium titanate or similar compounds, which exhibits strong dielectric properties. This enables the storage of electric charge efficiently, making them a crucial component in various applications, including filters, resonant circuits, and power supplies.
