Film Capacitors

A film capacitor, also known as a plastic film capacitor, polyester capacitor, polypropylene capacitor, plastic film dielectric capacitor, or film dielectric capacitor, is a type of capacitor which utilizes a plastic film as the dielectric. The film capacitor is most commonly used because of its high insulation resistance and low loss, long life, and low dielectric absorption. The film capacitor also offers excellent electrical properties, such as low electrical leakage and high dielectric constant.

225PHC850K Application Field

The 225PHC850K is a plastic-film capacitor that utilizes PEEK polyethersulfone (PESU) film as the dielectric material. This PESU film is a type of bipolar plastic film which offers excellent electrical performance, especially when used for bypass, coupling, and filtering applications. This type of capacitor is suitable for use in a variety of applications, from medium-to-high voltage power electronics, power-supply, and motor control circuits. In addition, the 225PHC850K can also be used in 1-phase or 2-phase adjustable speed drive (ASD) applications requiring Hi/Lo switching.

225PHC850K Working Principle

The 225PHC850K works by Polarizing the PESU polymer film to create a thin dielectric layer. This polarization process creates high breakdown voltage, excellent dielectric and low ESR values. As such, the 225PHC850K offers excellent performance in a variety of high-performance applications. As a result, it is highly suitable for use as a bypass filter capacitor in high-power bi-directional circuits, such as regenerative inverter drive circuits and unipolar switched-mode power supplies (SMPSs) or motor control applications.
