According to the kind of plastic film is divided into: poly ether capacitor (also known as Mylar capacitor), polypropylene capacitor (also known as PP capacitor), polystyrene capacitor (also known as PS capacitor) and poly carbonate capacitor. The structure of capacitor and the same medium, polyester or polystyrene etc.. Polyester film capacitor has high dielectric constant, small volume, large capacity and good stability. It is suitable to be used as bypass capacitor. Polystyrene film capacitors, dielectric loss, high insulation resistance, but the temperature coefficient is large, can be used in high frequency circuits.
A thin film capacitor is a capacitor constructed from a metal foil as an electrode and wound with a plastic film, such as poly (ethyl ester), polypropylene, polystyrene, or polycarbonate, that is folded from both ends to form a cylindrical structure. According to the kind of plastic film, they are also called poly ester capacitor (also known as Mylar capacitor), polypropylene capacitor (also known as PP capacitor), polystyrene capacitor (also known as PS capacitor) and poly carbonate capacitor.
Film capacitors, also called Mylar capacitors, are ultra thin poly (poly) chloride or poly (propylene) thin films used as dielectric!
