Working Principle

The working principle of F17724152230 film capacitors is based on the interference effect between two different insulators. The whole capacitor consists of two bipolar insulators of different materials. One is called the medium layer, which is made of polyester or polypropylene film. The other layer is the electrode layer, which is composed of metal, and the two layers are superimposed. The work of the capacitor is to capacitor energy through the effect of electrical interference.

The working principle of the F17724152230 film capacitor is that the dielectric material with the metal film layer on its two sides is used as the component, which forms a capacitor structure. The AC through the metal film layer produces inductive voltage action, which will cause the dielectric material to be subjected to a certain alternating electric field, thus forming electrostatic induction field. The electric field and the capacitor k Va effect formed by the medium layer and the electrode layer will change the current, so as to achieve the purpose of charging and discharging.
