Film Capacitors

Film capacitors, also known as polyester capacitors or plastic capacitors, are capacitors whose anode and cathode electrodes are separated by a thin insulating plastic film. They are mainly used in electronic applications requiring high accuracy, good temperature stability and long life.

The PHE840MD6220KD13R06L2 film capacitor is a high-grade, high-efficiency capacitor that is widely used in a variety of applications. The capacitor contains a multi-layer polyester film dielectric and is rated for a capacitance of 840 microfarads, a working voltage of 630 volts, and a dielectric strength of 660 volts.

Application Field

The PHE840MD6220KD13R06L2 film capacitor has a wide range of applications in electronics and power conditioning in automotive, aerospace, and industrial applications. The capacitor is ideal for high-performance systems in audio and RF applications, such as amplifiers, pre-amps, and other related components. It is also suitable for filtering, snubbing and other power supply applications, as well as in communication systems and other forms of power generation.

Working Principle

The working principle of film capacitors is essentially the same as conventional electrolytic capacitors, meaning that they store and produce electrical energy. However, film capacitors typically use a dielectric consisting of various types of plastic (polyester, polypropylene, Mylar, etc.) to provide greater stability in temperature and environment, allowing for more precise and accurate operation. The actual capacitance value of a film capacitor is determined by the physical dimensions of the dielectric material, as well as its electrical and chemical properties.

The film capacitor has a relatively high, stable voltage rating and is able to withstand extreme temperature ranges, making it ideal for use in high-performance applications. Additionally, the capacitor consists of low-loss insulation materials which provide enhanced frequency characteristics and low dielectric absorption. Finally, film capacitors can be operated in either DC or AC, making them one of the most popular choices for many modern electronics applications.
