Ceramic capacitors are a type of capacitor that utilizes ceramic materials to store electrical charge. They are commonly used in power supplies, filtering circuits, and other applications where a stable, low-ESR (equivalent series resistance) component is required. The MLCC stands for Multilayer Ceramic Capacitor, which refers specifically to a type of ceramic capacitor constructed from multiple layers of ceramic material that are alternately interleaved with electrodes. This design allows for higher capacitance values in a smaller package size compared to other types of capacitors. Applications of ceramic capacitors include: Power supplies: MLCCs are often used in power supply circuits to filter out high-frequency noise and ripple. Filtering circuits: Ceramic capacitors can be used to filter out unwanted signals in electronic circuits. Decoupling: They can also be used as decoupling capacitors to block DC voltage from entering sensitive components.
