Are polyester capacitors metal film capacitors? |Focus on mid-to-high-end brand capacitor manufacturers

Polyester capacitors, called CL11, are generally dark green and are widely used in DC and pulsating circuits in radio and television products, communication equipment, energy-saving lamps for displays, and other fields. So are polyester capacitors metal film capacitors? The answer is: Polyester capacitors are not metal film capacitors, but metal foil capacitors. Metal film capacitors and metal foil capacitors are all thin film capacitors. A film capacitor refers to a type of capacitor that uses an organic film as a dielectric and a metal foil (or a metal layer formed by vapor deposition on the film) as an electrode, which is wound or laminated. It has the characteristics of non-polarity, high insulation resistance, low dielectric loss and excellent frequency characteristics. Dacron capacitors are film capacitors that are wound or laminated using metal foil as electrodes, and belong to the metal foil type film capacitors. The metallized film capacitor is to vapor-deposit a metal layer on the surface of the film as the dielectric as an electrode, which is referred to as a metal film capacitor for short.
