Metallized Polyester Film Capacitor Vs Ceramic

Metalized polyester capacitors mkt data sheets parameter search key technical data general information.

Metallized polyester film capacitor vs ceramic. Made of ceramic material as the dielectric and metal as the electrodes ceramic capacitors come in a variety of shapes and sizes. Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. The most common dielectric materials used in the construction of plastic film capacitors are polypropylene and polyester. They are generally less expensive than other capacitors and carry lower capacitances couple of µf max which makes them used often during low capacitance requirements in noise harmonics filtering and suppression applications.

Polyester film capacitors are film capacitors using a dielectric made of the thermoplastic polar polymer material polyethylene terephthalate pet trade names hostaphan or mylar from the polyester family. This type of capacitor is very inexpensive to build and most look very much like figure 1. Although a very successful and useful form of film capacitor this type is no longer made because the manufacturer of the film. The core difference between these capacitor types is the material used as the dielectric and the proper dielectric must be chosen according to the application.
