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.

Metallized polyester film capacitor vs ceramic.

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. Other dielectrics used in the construction of film capacitors include polycarbonate polystyrene polytetrafluoroethylene ptfe polyethylene naphthalate pen polyphenylene sulphide pps polyimide and paper. Polyester pet film capacitors. Although a very successful and useful form of film capacitor this type is no longer made because the manufacturer of the film.

Polyester film capacitor one downside of this type of film capacitor is that it can introduce noise when used in applications where there is vibration. The most common dielectric materials used in the construction of plastic film capacitors are polypropylene and polyester. Read more about polyester capacitors polycarbonate pc. Metalized polyester capacitors mkt data sheets parameter search key technical data general information.

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. 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. There are a few types of plastic film capacitors including mylar polycarbonate polyester and. Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies.
