The purchase of thin film capacitors depends on the application environment to choose the appropriate type of capacitor components. Today, we will learn about the use and advantages of polyester film capacitors?
Polyester film capacitor belongs to organic film capacitor class, also known as polyester capacitor. It is made of metal foil or metal film as electrode and polyethylene terephthalate (PET) film as medium by winding and sealing in plastic shell. In some capacitors, the core is wrapped with colored epoxy resin. The capacitor made of metal film electrode is called metallized polyester film capacitor.
Polyester film capacitors have excellent mechanical, electrical and optical properties, so they have a wide range of applications, such as photographic film, magnetic tape, video tape, microfilm, packaging film and capacitor, etc.
Polyester film capacitor adopts metallized polyester film, non inductive winding structure, and has wide capacity range, small volume and light weight. Therefore, the installation is more convenient, not only that, polyester film capacitor self-healing good, long service life. At the same time, the polyester film capacitor is also encapsulated with flame retardant epoxy powder.
From a professional point of view, polyester film capacitor is the most suitable choice for some occasions where stability is strictly required due to its high stability. For example, in electronic instruments or meters and radios, it can be used as a coupling or bypass.
For polyester film capacitor, not only has the above advantages, but also has strong heat resistance and moisture resistance, but also has a certain degree of voltage resistance.
