Film Capacitors are one of the most widely used electronic components in the industry today. This article will discuss the application field and working principle of 472PPB162K, a particular type of film capacitor.

Background

Film capacitors, which are also known as film dielectric capacitors, are a type of electronic device that has the capability to store electrical energy. They are mainly used in a wide variety of power electronic applications such as power supplies, motor drives, inverters, etc. They have the capability to provide a relatively high level of capacitance while being very compact. Furthermore, they offer excellent electrical characteristics, such as low ESR, high ripple current, low noise, and wide frequency range.

472PPB162K Application Field

The 472PPB162K is a type of film capacitor that is especially designed for use in auxiliary power supplies, voltage regulators, and other power applications. It is particularly popular among designers who need good electrical characteristics in a relatively small form factor. This type of film capacitor is also well-suited for applications where a low ESR and high ripple current are required. In addition, it provides excellent mechanical support when used in applications where physical shock may be encountered.

Working Principle

The working principle of a film capacitor is based on the same principle as that of other capacitor types. In a film capacitor, the dielectric material is a thin film, which is made of polypropylene, polyester, or polyethylene. The metal electrodes are placed on either side of the film. When an electrical potential is applied across the two electrodes, a static electric charge builds up. This charge is what gives the capacitor its ability to store energy.

In a 472PPB162K film capacitor, the polyester dielectric is designed with a special technology called metallized technology. This technology makes the device very thin and compact. The metallization process involves the deposition of a thin metal film onto the surface of the dielectric material, which helps to prevent dielectric breakdown. This type of film capacitor also has excellent electrical characteristics such as low ESR, high ripple current, and wide frequency range.

Conclusion

472PPB162K is a type of film capacitor that is especially designed for use in auxiliary power supplies, voltage regulators, and other power applications. It has excellent electrical characteristics such as low ESR, high ripple current, and wide frequency range. Furthermore, it provides great mechanical support when used in applications where physical shock may be encountered. Therefore, it is a very popular choice among designers who need good electrical characteristics in a relatively small form factor.
