Dingfeng Capacitor -- Advances in metalized film capacitor technology

Jan 5,2020

With the development of science and technology and the maturity of technology, we are constantly improving the quality of our capacitors!


With the in-depth study of the breakdown mechanism of polymer and the self-healing mechanism of metalized electrodes, some new materials and processes have been or gradually applied to the field of capacitors. Such as split electrode metalized film, the application of split electrode metalized film greatly extends the concept of self-healing, and provides secondary protection for metalized film capacitors.


It is made by block evaporation and non-uniform evaporation and consists of countless divided film blocks. Different film blocks are connected only by very thin vapor-deposited metal wires, such as composite films. Currently, the films used in metalized film capacitors include polypropylene, polyester, and polycarbonate. These materials have their own advantages and disadvantages, and their dielectric capacitors have reached or near their limit storage energy density. Composite dielectric film is a new type of energy storage medium. Its principle is to compound a layer of very thin dielectric material on a base film to make it have better performance.


As a manufacturer of metalized film capacitors, we pay great attention to quality. Based on quality, we are your reliable film capacitor manufacturer.
