1. Is the thickness of the film in the film capacitor the thicker the better?

No, the thicker the dielectric (film), the higher the voltage it can withstand, and vice versa, the thinner the film, the lower the voltage it can withstand. Moreover, the capacitance of the film is related to the metal coating. The thicker the metal coating, the stronger the overcurrent capability, but the result is the greater the heat generation. On the contrary, the thinner the metal coating, the weaker the overcurrent capability, the lower the heat generation. When choosing film capacitors, one should not only consider the thickness of the capacitor. The film capacitor should be selected according to the actual needs and related criteria.

2. Why would the capacitance of film capacitor decrease?

The capacitance of the film capacitor depends on the area of the film metal layer, so the decrease in capacitance is mainly caused by the reduction of the area of the metal plating layer affected by external factors.

In the capacitor manufacturing process, there is a trace of air between the film layers, and when the capacitor is working, the metal coating of the metalized film of ozone is oxidized immediately after encountering the oxygen decomposed by ozone, and the transparent and non-conductive metal oxides ZnO and Al2O3 are generated. The actual manifestation is that the area of the plate is reduced, and the capacitance of the capacitor is reduced. Therefore, eliminating or reducing the air between the membrane layers can slow down the capacitance decay.
