The structure and composition of the CBB capacitor:

 

The principle of CBB capacitance is actually relatively simple. It is two parallel strip plate, middle insulation medium composition core, two plate each has one elicitation, that is two electrode.

 

Metal deposits of CBB metallized film are deposited on thin films by vacuum evaporation, with a thickness of only a few tens of nanometers. When there are defects and impurities in the medium, the local electric shock may occur. The energy produced by the electric arc discharge at the electric shock is evaporated and penetrated. The electrical performance of the capacitor can be restored to normal after the points are separated from the surrounding plates.

CBB capacitor structure: a negative temperature coefficient nonpolar capacitor made of non polar polypropylene film. There are two types of non sealed (commonly used colored resin lacquer) and sealed (sealed with metal or plastic housing).
