Working Principle of BFC237523362

A film capacitor consists of two or more layers of thin dielectric film, an conductive layer coated on both sides or several layers of metallized foil electrodes, a copper-clad steel frame or plastic frame, and a varnish coating surrounding the structure. When alternating current (AC) runs through the film capacitor, an electrostatic field or a magnetic field is generated between the two electrodes, to store electrical charges. The larger the area of the electrodes and the thickness of the dielectric film, the higher the capacitance of the film capacitor and the more charge it can store.

In addition, the capacitance of the film capacitor is also related to its other parameters. When the frequency of input signal changes, its impedance will also change accordingly, resulting in a change of capacitance. When the temperature increases, the thickness of the dielectric film will decrease due to the expansion of the material, causing the dielectric loss to be higher and the capacitance to be lower. Due to its stable capacitance characteristics, the film capacitor is widely used in a variety of applications.
