Film capacitors, also known as plastic film capacitors, refer to capacitors with plastic film as the medium for storing electricity. The capacitance of such capacitors is usually low, in the range of several tens of picofarads to 1 microfarad, and its features are mainly high dielectric strength, good insulation stability, working temperature up to 130℃, small size and light weight. The BFC246719563 application field is mainly in electronic equipment, TVs, computers, air conditioners, refrigerators, washing machines, etc. Its working principle is mainly due to the dielectric medium, that is, the insulating film made of polypropylene is used as the medium of dielectric, and the electric field is formed between the two electrode plates. The electric field affects the medium, causing the media molecules to shift to one side and form positive and negative polarization, resulting in the formation of a dipole layer between the two electrodes, forming an electric double layer. With the change of the applied voltage, the forming and destruction of the electric double layer periodically changes, and the corresponding strength of the electric field is changed, which causes the electric charge to be stored in the double layer and is released to form energy. Finally, electricity, energy and information are produced, which is the main working principle of film capacitors.
