Metallized Polyester Film Capacitor Vs Ceramic

There are a few types of plastic film capacitors including mylar polycarbonate polyester and.

Metallized polyester film capacitor vs ceramic.

Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. There are many types of film capacitors including polyester film metallized film polypropylene film ptfe film and polystyrene film. Other dielectrics used in the construction of film capacitors include polycarbonate polystyrene polytetrafluoroethylene ptfe polyethylene naphthalate pen polyphenylene sulphide pps polyimide and paper. 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.

This type of capacitor is very inexpensive to build and most look very much like figure 1. 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. They are manufactured both as metallized wound and stacked versions as well as film foil types. Read more about polyester capacitors polycarbonate pc.
