With the continuous improvement of the performance and technology of film capacitors, its prospects are very considerable. Film capacitors are also called plastic film capacitors. It uses a plastic film as the dielectric. There are many types of capacitors depending on the dielectric.
Apart from high insulation resistance, low dielectric loss, and excellent frequency characteristics, film capacitors also have good temperature characteristics. Unlike other capacitors, its dielectric material is high-temperature polypropylene film. Its temperature characteristics allow it to swim back and forth between -40°C and 105°C without being affected. The role of film capacitors is the same as that of all capacitors, that is, to hold the charge.
It has a so-called self-healing action, that is, if a tiny part of the electrode is short-circuited due to the fragile electrical boundary, the electrode metal around the short-circuit part will be affected by the electrostatic energy or short-circuit current carried by the capacitor at that time. The current causes a larger area of melting and evaporation to restore the insulation, so that the capacitor resumes the function of the capacitor again. That is to say, it can heal itself in an instant.
Choosing the correct capacitor can make the best of its advantages. To purchase film capacitors, you should choose a reliable manufacturer.
