Customer ServiceFilm capacitors. Film capacitors use a thin plastic film as a dielectric. Conducting plates can be implemented either as foil layers or as two thin layers of metallization, one on each side of the plastic film. The plastic used for the dielectric determines the characteristics of the capacitors. Film capacitors come in many forms:
Customer ServiceCharacteristics. Film capacitors are extensively used in different applications due to their superior characteristics. This type of capacitor is not polarized, so it can be apt for AC signal as well as power use.

In this standard, the electrical characteristics of capacitors are described by an idealized series-equivalent circuit with electrical components which model all ohmic losses, capacitive and inductive parameters of a film capacitor:
The first difference which is quite evident between these three capacitors is the type of dielectric used and their construction. While the film capacitors use thin sheets of plastic films, ceramic capacitors have sheets made out of ceramic material as the dielectric. Both of them are bipolar in nature.
Especially for applications with high current pulse loads or high AC loads in electrical systems, heavy-duty film capacitors, here called "power capacitors", are available with dielectric ratings of several kilovolts. But the manufacture of film capacitors does have a critical dependency on the materials supply chain.
Standardized conditions for film capacitors are a measuring frequency of 1 kHz and a temperature of 20 °C. The percentage of allowed deviation of the capacitance from the rated value is called capacitance tolerance. The actual capacitance value of a capacitor should be within the tolerance limits, or the capacitor is out of specification.
Although the materials and the construction of power capacitors are mostly similar to the smaller film capacitors, they are specified and marketed differently for historical reasons. The "film capacitors" were developed together with the growing market of broadcast and electronic equipment technology in the mid-20th century.
