474PPB630K

Film Capacitors

The 474PPB630K is a type of film capacitor, also known as polyester film capacitor. It belongs to a larger class of capacitors called film capacitors, which are electrical components that store energy within an electric field and use thin film as an insulating medium. Film capacitors are used in a variety of applications due to their small size, insulation properties, impressive capacitance, and good high frequency response.

474PPB630K Application Field

The 474PPB630K offers a wide range of uses and benefits, making it suitable for use in different applications. It is often used in power electronic circuits, EMI filters, signal coupling networks, and lamp circuits. With a wide range of operating temperatures, ranging from -40 to +85°C, the 474PPB630K is also suitable for automotive and marine applications.

474PPB630K Working Principle

The 474PPB630K works on the same principle as other film capacitors. It consists of an insulating medium in the form of thin dielectric films, including polypropylene, polyester, and polycarbonate, with a low dissipation factor or Dielectric Loss. Between the two conductors, a thin layer of dielectric films is placed, which forms two capacitors connected in series, creating a “capacitive divider”. By having two capacitors connected in series, the 474PPB630K can store more energy than a single capacitor.

Summary

The 474PPB630K is a film capacitor and a type of polyester film capacitor that offers a range of properties and benefits. Its use extends from power electronic circuits to membrane circuits, and it is suitable for both automotive and marine applications. The principle of the 474PPB630K capacitor is the same as other film capacitors, and its energy capacity is more than a single capacitor by connecting two capacitors in series, forming acapacitive divider.
