Film capacitors are made out of two pieces of plastic film covered with metallic electrodes, wound into a cylindrical shaped winding, with terminals attached, and then encapsulated. In general, film capacitors are not polarized, so the two terminals are interchangeable. There are two different types of plastic film capacitors, made with two different electrode configurations:

6 FAQs about [Capacitor film field survey]
Are BOPP films suitable for DC metallized film capacitors?
The fundamental and applied properties of BOPP films required for application in state-of-the-art DC metallized film capacitors are reviewed, highlighting aspects related to high temperature operation, base PP properties and film processing.
Are Bopp capacitors reliable at high field?
The literature on the conduction and reliability of BOPP capacitor films at high field is vast, but is mostly focused on relatively high film thicknesses, generally from 6 µm to 25 µm. No literature was found by the authors investigating ultra-thin BOPP (2–4 µm), or for film thickness below 5 µm in general.
How reliable are film capacitors?
The most important reliability feature of film capacitors is their self-healing capability, i.e. their abil-ity to clear faults (such as pores or impurities in the film) under the influence of a voltage. The metal coatings, vacuum-deposited directly onto the plastic film, are only 20 50 nm thick.
What is a polypropylene film capacitor?
Polypropylene film capacitors are often used in applications in which negligible discharge rates are required, because of their high insulation resistance (IR) and low conduction current, or leakage current (LC).
Can polypropylene capacitor films withstand electrical stresses?
A broad study of the performance of a modern polypropylene capacitor film is therefore warranted to serve as a baseline for further materials development, and to demonstrate the capability of BOPP films to withstand electrical stresses unrealistic for almost any other type of insulation.
What is a capacitor-grade BOPP film?
2 CAPACITOR FILM PROCESSING Capacitor-grade BOPP film is made of highly isotactic polypropylene. The molecular structure of PP with higher isotacticity is more regular. This enables packing that is more compact during crystallization, and thus enables the production of high crystalline films with reduced losses and conductivity .
