The history of thin film capacitance
Jan 03, 2019

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


In 1876, Fitzgerald invented paper capacitor, which marked the birth of thin film capacitor. With the passage of time and the development of science and technology, the types, process materials and functions of thin film capacitor became various. Now organic medium can be divided into polyethylene, polystyrene, polytetrafluoroethylene, polypropylene, polyester, polycarbonate, polyimide, polyphenylene oxide, etc., because of their high insulation resistance, excellent frequency characteristic (broad frequency response), the excellent properties of small dielectric loss, is widely used in audio, speakers, automobile and other industries, most polypropylene film capacitor is used in it and polyester film capacitor.


At present, thin film capacitors are developing rapidly, and the process and manufacturing process are constantly improving, so as to achieve better performance and lower price and better experience for people.
