A film capacitor is a capacitor that uses a thin plastic film as the dielectric. They are relatively cheap, stable over time and have low self-inductance and ESR, while some film capacitors can withstand large reactive power values.
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 also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life. The film capacitor uses a thin dielectric material with the other side of the capacitor metalized. Depending on the application, the film capacitor is rolled into thin films ...

The characteristics and application possibilities of film capacitors are affected so strongly by the dielectric used that capacitors are grouped and designated according to the type of dielectric. Short identification codes for the type of construction, describing the dielectric and the basic tech-
When voltage is applied between facing conductors, the insulator (or space) sandwiched between them will cause dielectric polarization by electrostatic induction, thus leading to the accumulation of electric charges (charging). The capacitor is a device (part) that performs this charging and discharging of accumulated charges as its function.
Film capacitors are build up by two electrodes (the capacitor plates) with plastic dielectric …
ferred precision-capacitor dielec-tric and is the dielectric film in FCP chip capacitors. AC Voltage Operation: You can use all CDE film capacitors with either AC or DC voltages or a combination of the two. The rules for successful application are: 1) don''t exceed the dielec-tric''s voltage capability; 2) keep the capacitor cool, and 3) don''t

Higher Voltage Capacitors Using Film Dielectric Technology Ralph M. Kerrigan NWL Riviera Beach, Florida rkerriga@nwl This presentation describes capacitors that are manufactured with film dielectric technology and applied in higher voltage systems. We are defining higher voltage systems as those starting at about 800 Volts DC and 600 volts AC Major Film …
These dielectric films for capacitors have a high level of rigidity for good insulation between the electrodes and constant thermomechanical characteristics for stable capacitor performance. They are used in particular in the equipment of electric vehicles, thereby contributing to …
Film dielectric capacitors enabled with large breakdown field strength and high energy density play a key role for compact and integrated power systems. Nevertheless, the energy storage efficiency is always sacrificed as we tried to increase the energy density. This trade-off between energy density and efficiency means significant energy dissipation and …

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 …
Film dielectric capacitors have two different types of electrodes. These are a discrete foil, which is typically aluminum or a very thin metallization that is vacuum deposited on the film. In addition to two different electrodes, we also can divide the capacitors into AC and DC applications. This produces a two by two matrix. We can see for AC ...
