Film Capacitors

PME271M622KR30 is a film capacitor designed and manufactured by Pulse, a leader in electronics components production. It is a medium power capacitor which is suitable for general use for applications in the temperature range of -40C to +105C. It is also capable of surviving high temperature applications of up to +125C. This capacitor is used in applications such as: DC blocking and filtering; snubbing; AC mains coupling; power supplies; low power audio; RF bypassing; and amplifier tuning.

Working Principle

The PME271M622KR30 works on the principle of electrostatic energy storage. The capacitor has two metal plates with a thin dielectric film separating them. When a charge is applied to the capacitor, an electrical field is generated between the two plates, which stores energy and acts like a short-term power source. The amount of charge that the capacitor can store depends on the plate area and the thickness of the dielectric material between the two plates. This makes film capacitors ideal for storing energy over short periods.

In addition, the PME271M622KR30 also has a wide temperature operating range which makes it suitable for a range of applications. The temperature rating of the capacitor is measured by its temperatures coefficient or “TK” — the lower this number, the greater the temperature resistance of the capacitor. The PME271M622KR30 has a temperature coefficient of +125C, making it suitable for high temperature applications.

Applications

The PME271M622KR30 is mainly used in power supplies and DC-DC converter applications. It is also used in energy storage applications such as power factor correction, power smoothing and for the buffering of high-peak currents. It is well-suited for applications in home appliances, such as refrigerators, microwaves, and washing machines.

The PME271M622KR30 can also be used in professional audio equipment, such as amplifiers and DJ mixers, to protect the sound signal from high frequencies and distortio. Film capacitors are also used in motors and power supplies for filtering low frequencies for a clean, steady supply.

Conclusion

The PME271M622KR30 is a film capacitor which is suitable for a wide range of applications. It is capable of storing energy over short periods and has a wide temperature operating range, making it well-suited for high temperature applications. This capacitor is mainly used in power supplies, DC-DC converters, energy storage applications and professional audio equipment.
