Film Capacitors

Film capacitors (or plastic film capacitors) are devices that are typically used when large capacitance values and/or high voltage ratings are required. They are composed of thin plastic films which serve as the dielectric material, an electrode, and lead wires. These capacitors are available in different styles and with various terminations, ratings, and features.

F339MX254731MPI2T0 is a reliable film capacitors that is available in a variety of sizes and configurations. It offers a capacitance range of 20pF to 1nF and a voltage rating up to 1000V DC.

Working Principle and Construction

Film capacitors have a stable electrical characteristic because of their unique construction. The dielectric is a formed thin polymer film, such as polycarbonates, polyesters, or even polypropylene. The electrodes are typically made of aluminum foil, and the leads are designed to be mechanically strong.

The construction is similar to that of a conventional aluminum electrolytic capacitor. The two main differences are the size of the capacitor and the dielectric material. In film capacitors, the dielectric material is much thinner than the electrolytic one, which gives them better insulation, stable capacitance, and lower losses.

The capacitance of a film capacitor is determined by its construction. Specifically, the capacitance is a function of the area of the electrodes and the distance between them, as well as the thickness of the dielectric layer. The voltage rating is determined by the insulation resistance of the dielectric material.
