The film/foil construction is mainly used for capacitors with smaller capacitance (100pF through 0.1µF). The advantage of this construction is the easy contactability of the metal foil electrodes and the good pulse strength. A breakdown in the dielectric film of a F capacitor leads to an irreversible short circuit and thus, to failure.

The main types of film capacitor structures are winded and layered. Winded film capacitors contain a polymer film that is wound and pressed, and inserted into a case. Layered film capacitors contain multiple layers of polymer film inserted into a case. Winded film capacitors are most commonly used now, as they have a simple structure.
Construction of Film Capacitors The first step to constructing a capacitor film is getting a thin layer of the plastic film even with an additional layer. So, the thickness you choose determines the capacitance value of the device and layer of paper. And the thickness of your plastic film affects the distance between electrodes.
The polyester capacitor is designed with two metal plates where the polyester film is arranged between them; otherwise, a metalized film can be placed over the insulator. The polyester capacitor capacitance ranges from 1nF -15µF and works from 50 to 1500V.
Power ceramic capacitors range from 2 kV to 100 kV. They have advantage over film capacitors when it comes to small values. While film capacitors are not made below 0.1 μF, high voltage ceramic capacitors are available even as 0.5 pF or 1 pF. Another advantage is small pitch of 2.5 mm, 5 mm, 7.5 mm etc., not possible with film capacitors.
CONSTRUCTION OF CAPACITORS CELLS Film capacitors are build up by two electrodes (the capacitor plates) with plastic dielectric material in between. The type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is evaporated on the plastic dielectric material.
