Ceramic capacitors, also known as ceramic caps, are a type of component used in electronic circuits. They have been designed to provide a wide range of capacitance values while maintaining relatively low costs. This makes them a popular choice for many electronic applications. Their construction involves placing a dielectric material between two metal plates, creating an electric field when a voltage is applied. The dielectric materials used can vary, including types like barium titanate, which exhibits high dielectric constants and is often utilized in multilayer ceramic capacitors (MLCCs). MLCCs, in particular, have become increasingly prevalent due to their compact size and ability to store electrical charge. These components consist of multiple layers of ceramic material, each separated by thin metal electrodes, allowing for higher capacitance values while maintaining a smaller footprint. Their applications range from consumer electronics to industrial devices, often used as filters or decoupling capacitors in power supplies and signal processing circuits. Overall, ceramic capacitors like MLCCs have become indispensable components in modern electronic systems due to their versatility and performance characteristics.
