Historical development of film capacitors

We are now using a variety of electronic devices, the convenience of science and technology has greatly saved our time and energy, which is due to the development of science and technology, but also many predecessors have invented many electronic components.

In 1876, the British Fitzgerald invented the paper dielectric capacitor, which marked the birth offilm capacitors, and then with the passage of time, the development of science and technology, the types of film capacitors, process materials, functions and so on have become diverse. Today, organic media can be divided into polyethylene, polystyrene, polytetrafluoroethylene, polypropylene, polyester, polycarbonate, polyimide, polyphenylene ether and so on, because of their high insulation impedance, excellent frequency response (wide frequency response), medium loss and other excellent characteristics, are widely used in audio, speaker, automobile and other industries. Among them, polypropylene film capacitors and polyester film capacitors are the most widely used.

Nowadays, film capacitors are developing rapidly, and the process and process are being improved constantly in order to achieve better performance, lower price and better experience.
