Ceramic capacitors, often referred to as Cerams or Cer Caps, are a type of fixed capacitor used in electronic circuits. They consist of two metal plates separated by a ceramic insulator. The dielectric material is typically made from a mixture of ceramic and metal oxides, which allows the capacitor to store electrical energy. The main advantage of ceramic capacitors is their reliability, as they can withstand high temperatures without degrading. This makes them suitable for use in harsh environments, such as those found in automotive or aerospace applications. Additionally, ceramic capacitors have a low self-inductance and are generally inexpensive compared to other types of capacitors. Despite these limitations, ceramic capacitors remain widely used due to their low cost and high reliability. They are commonly found in applications such as power supplies, filters, and coupling circuits.
