Film capacitors, also known as film dielectric capacitors, are components that use plastic film as the dielectric. Generally, they are composed of two metal foil electrodes and a plastic film. The metal foil is made of copper or aluminum foil, and the plastic film is combed by PET, PEN, or some other non-conductive material. They are usually cylindrical, its size is much larger than ordinary electrolytic capacitors. They can have long lifetimes, wide operating temperature ranges, and excellent temperature characteristics.

QXP2E155KRP7FT is a typical metalized film capacitor. This kind of capacitor belongs to metallized polyester capacitor, which is one of the most widely used film capacitors. Specifically, the metalized film capacitor made of the superb, finely-dispersed particles of metal, the controlled dielectric was made by the vacuum evaporation of aluminum on the surface of polyester film under high temperature. It has capability to suppress external interference, no epoxy resin is involved in the production process, and its voltage proof can be as high as 5KV. This capacitor can be used in various occasions where dielectric film capacitor is necessary.

QXP2E155KRP7FT application field mainly covers common power electronics and power supply, low frequency and high frequency coupling, decoupling, and dc link between power electronics and the loads. Generally, The working principle of this kind of capacitor is as follows: the metal layer and the dielectric layer are layered together and pressed tightly. During application, it has the character of dielectric to form a large area of capacitor with its cylindrical structure. When the AC/DC voltage is applied on the electrodes, an electric field is formed between the two layers, so electric current appears. This current is relatively smoothed and stable, and its output and storage capability is perfectly applicable for electric transmission and storage.

In conclusion, QXP2E155KRP7FT is a typical film capacitor, and it is mainly used in power electronics and power supply, low frequency and high frequency coupling, decoupling, and dc link between power electronics and the loads. Its working principle is to use the character of dielectric to form a large area of capacitor with its cylindrical structure, and its metal layer and dielectric layer are layered together and pressed tightly.
