Film Capacitors Selection Guide: Types, Features, Applications
4 · Metal foil capacitors provide easy electrode connection and good surge resistance, but may easily sustain damage due to dielectric breakdown. Metallized film capacitors use two plastic films which have been coated with a very thin layer of aluminum (metallized), which serves as the electrode.
Metallized film capacitors used for EMI filtering: A reliability review
Film/foil capacitors consist of alternating layers of polymer or paper film and metal foil that are wound together. The foils are typically on the order of 6 μm in thickness, giving them higher current handling capabilities than a similarly sized metallized film capacitor [2, 3]. However, the thick metal foils prevent these capacitors from ...
Electronics/Capacitors
Film/foil capacitors or metal foil capacitors use two plastic films as the dielectric. Each film is covered with a thin metal foil, mostly aluminium, to form the electrodes. The advantage of this construction is the ease of connecting the metal foil electrodes, along with an excellent current pulse strength.
A Guide to Types of Film Capacitors and their Applications
Teflon capacitors. Teflon film capacitors match polystyrene''s performance and excel at high temperatures. These capacitors are moisture-resistant with a low dielectric absorption of around 0.02%. Teflon film capacitors have higher price limits and are mostly used in mission-critical applications such as aerospace.

Types of capacitors and how they are made
The foil-paper-foil winding is then placed in the external housing of the capacitor unit, often called a ''can.'' Next, an electrolyte solution is wicked through the winding via the paper layer. The capacitor can is then sealed with the deck and is thermally aged to repair any dielectric faults and monitor electric properties.

It typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting vertically through the jar lid to make contact with the inner foil. It was the original form of the …
Leyden jar
A Leyden jar (or Leiden jar, or archaically, Kleistian jar) is an electrical component that stores a high-voltage electric charge (from an external source) between electrical conductors on the inside and outside of a glass jar. It typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting …
Film/foil capacitors
In the case of film/foil capacitors, the electrode is not applied as for the metallized capacitors, but is wound with the dielectric as a metal foil. The film/foil construction is mainly used for capacitors with smaller capacitance value. The advantage of this construction principle is the easy contactability of the metal foil electrodes and the good pulse strength.
