Film capacitors, or film dielectric capacitors, are common passive components of electrical and electronic components that store electrical energy mainly using plastic films, metal film sheets, and other materials made with high-precision processing technology. The BFC237022393 series of is a kind of specialized film capacitor. This article introduces its application field and working principle.

Applications

BFC237022393 series of film capacitors are widely used in various fields, including electrical equipment, power transmission and distribution, and inverter applications. Its wide range of applications is mainly due to its excellent electrical performance and excellent mechanical performance. Among these features, its superior electrical performance includes its ability to maintain stable performance in high temperatures of up to 125oC; its low dissipation factor; its low noise and interference performance; its high-rated voltage; its small volume and its high insulation performance.

The mechanical performance of the BFC237022393 is also quite good. This capacitors have a well-polished and smooth appearance due to its precision manufacturing process, and has a long service life because it is made of high-density dielectric materials which can greatly reduce mechanical damage. The BFC237022393 also includes an internal self-healing intermediate layer for better protection from short circuits.

Working Principle

The BFC237022393 series of film capacitors are composed of three layers of insulation material. The most common type of insulation materials used is polypropylene, polyester, and polyester-imide. The inner core and the outermost layer are made from the same type of film insulation material, while the middle layer is made from an independently produced polymer or polymer composite material.

The electricity storage and conduction of the BFC237022393 series mainly rely on a physical effect called the dielectric effect. In the BFC237022393 capacitor, when a voltage is applied, a uniform electric field is established between the inner and outer electrodes. The two electrodes form a closed circuit and the electric lines of force are passed between them following a number of accumulated storage layers, forming a dielectric polarization process.

When the voltage is removed, the electric fields decrease, the dielectric polarization stores the energy, and the electricity is discharged back and forth through the process of electric conduction. This process repeats again and again, allowing the capacitor to store and release electricity.

Conclusion

The BFC237022393 series of film capacitors have a wide range of applications because of their excellent electrical and mechanical performance. Their working principle is mainly based on the dielectric effect and electric conduction principle, which allows the capacitor to store and release electricity as needed.
