There is an old Chinese saying that people who dig wells do not forget to drink water. While we use various electronic equipment, we should not forget the efforts made by the predecessors to invent numerous electronic components. Axial film capacitor
s are now widely used in audio, speakers and other fields. While receiving its benefits, we also explore the source of axial film capacitors. In 1876, British D. Fitzgerald invented the paper capacitor. This marked the birth of film capacitors and the ancestor of axial film capacitors. Over time, organic dielectric materials have been widely used in the field of film capacitors due to their excellent performance. Organic media can be divided into polyethylene, polystyrene, polytetrafluoroethylene, polypropylene, polyester, polycarbonate, polyimide, polyphenylene ether, etc. Axial film capacitors produced by applying the above organic media have very excellent performance. The main characteristics are: non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and low dielectric loss. Its excellent performance determines that it can be widely used. Nowadays, polypropylene film capacitors and polyester film capacitors are the most used axial film capacitors used in the audio and speaker industries.
