Ceramic capacitors with a CAP CER MLCC designation are a type of component commonly used in electronic circuits due to their compact size, reliability, and relatively low cost. These components store electrical charge through the polarization of ceramic dielectric material between two electrodes, typically made of metal. The "MLCC" in the designation stands for Multilayer Ceramic Capacitor, indicating that these capacitors consist of multiple layers of ceramic material stacked together to achieve higher capacitance values within a smaller footprint.
