Ceramic capacitors are a type of passive electronic component used in various applications, particularly in power supply filtering and signal decoupling. These components consist of ceramic materials that exhibit dielectric properties allowing them to store electrical energy when voltage is applied across them. The MLCC stands for Multi-Layer Ceramic Capacitor, which further emphasizes its ability to hold multiple layers of these ceramic materials enhancing its capacitance values and compact size making it a widely used component in modern electronics.
