Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
Film capacitors are found for example in electric home appliances, electronic circuits in cars, industrial equipment, and power electronics devices. Depending on how the internal electrode is formed, film capacitors are divided into two main categories, namely foil electrode types and vapor deposition electrode (metallized film) types.
The performance of film capacitors differs, depending on the type of dielectric. It is therefore necessary to select the proper type according to the usage conditions. Wound type film capacitors with internal electrodes are made of metal foil (aluminum, tin, copper, etc.) sandwiched between plastic film layers and rolled up.
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. They are manufactured both as metallized wound and stacked versions, as well as film/foil types.
Like all capacitors, metallized film capacitors incorporate metal plates separated by a dielectric. Film capacitors are also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life.
Polycarbonate film capacitors are film capacitors with a dielectric made of the polymerized esters of carbonic acid and dihydric alcohols polycarbonate (PC), sometimes given the trademarked name Makrofol. They are manufactured as wound metallized as well as film/foil types.
