Film Capacitors

A film capacitor, also known as a polyester capacitor, is a type of capacitor that utilizes a thin film of dielectric as an insulator between two metal plates. In a film capacitor, the dielectric film is usually made from polypropylene. The film may also be made from other materials such as metal, ceramic, and polycarbonate. Film capacitors are used in a variety of applications, ranging from communications and power electronics to military and aerospace. They are especially well suited for high frequency applications.The MKT1818382015 is a type of film capacitor specifically designed for aerospace applications. It has a rated voltage of 18V and a maximum operating temperature of -20°C to +125°C. The MKT1818382015 has a copper-clad steel design and is made up of two layers of metalized polyester film that are insulated with an additional dielectric layer. The dielectric layer also provides protection from air leaks that can lead to electrical arcing and short circuits.The MKT1818382015 is most commonly used in applications such as radar systems, decouplers, and stabilizers. This type of capacitor is designed to withstand high vibration levels as well as high temperatures and pressure. It is also highly resistant to moisture, which makes it an ideal choice for use in harsh environments.The working principle of the MKT1818382015 is based on capacitance. A capacitor stores energy in the form of an electric field between two conductive plates. When a voltage is applied to the capacitor, the electric field between the two plates becomes stronger, storing more energy. This stored energy can then be released when the capacitor is disconnected from the power source.Film capacitors are known for their high capacitance values and low loss characteristics. This makes them ideal for use in high frequency applications, where the high capacitance values allow for high currents and low voltage losses. In addition, these capacitors are highly resistant to temperature and vibration, which makes them well suited for use in harsh environments.Overall, the MKT1818382015 is an ideal choice for use in aerospace applications. Its copper-clad steel construction and dielectric layer make it highly resistant to moisture and air leaks, while its high capacitance values and low voltage losses make it an ideal choice for use in high frequency applications. Furthermore, its high temperature and vibration resistance make it a suitable choice for use in harsh environments.
