Film Capacitors

Film capacitors, also known as plastic film capacitors more commonly, are capacitors whose dielectric is a plastic film. Usually these capacitors are made of a plastic film such as Polyester, Polycarbonate, Polypropylene and other related materials. Film capacitors have advantages over traditional paper or tantalum capacitors, such as better temperature stability and higher working voltage. The structure of film capacitors is simple, which consists of a metal film, a dielectric insulation film, wire leads and electrodes. Although, the opposition to electric current is lower than other types, it is not suitable for high-speed switching or high-amplitude high-frequency pulses, because of its rustling characteristic.

PHE840MR7220MR05R06L2 Application Field and Working Principle

The PHE840MR7220MR05R06L2 is an uncompensated, medium temperature film capacitor with a rating of 0.022μF, a rated voltage of 1000V and a tolerance of ±3%. It is a top choice for ultra-low loss, high voltage AC electronic applications in an ultra-compact case. The PHE840MR7220MR05R06L2 can be found in the application fields of high-end audio electronics, permanent magnet AC motors, power conversion systems, power factor correction, and others.

The working principle of the PHE840MR7220MR05R06L2 involves storing and releasing energy with a varying electrical field. In other words, it works by utilizing a dielectric material between two conducting plates and establishing a varying electrical field between them. The electrical field establishes the dielectric material’s polarization property, which is surprisingly higher than the material’s breakdown voltage. If a current is supplied, this causes a rapid change in the electric field and generates a change in the AC induced current, which is used to charge the capacitor. The capacitor stores and releases energy, based on the dielectric strength of the material.

In terms of dimensions and materials, the PHE840MR7220MR05R06L2 is only 7.2mm in diameter and 20mm in length, making it extremely compact. The material of the PHE840MR7220MR05R06L2 is polyester film, which is highly reliable, robust and stable in temperature. Its design includes straight-through terminals and a PTFE lead insulation, offering excellent temperature and environmental endurance.

In conclusion, the PHE840MR7220MR05R06L2 is an ideal choice for ultra-low loss, high-voltage AC electronic applications in an ultra-compact case. The working principle of this film capacitor involves storing and releasing energy with a varying electrical field, utilizing a dielectric material between two conducting plates.
