Ceramic capacitors, commonly known as Cer-cap or Cer, are a type of fixed capacitor with ceramic material used as its dielectric. They are designed to be compact, reliable, and inexpensive, making them widely used in electronic circuits. The key characteristics of ceramic capacitors include their ability to store electrical energy, provide filtering, and offer stable capacitance values over time and temperature. Ceramic capacitors can be classified into several types based on their construction, such as fixed or variable, and the type of ceramic material employed, like disc, tubular, or film.
