The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.
Vishay film capacitors uses the following film materials in their production: Polyester film offers a high dielectric constant, and a high dielectric strength. It has further excellent self-healing properties and good temperature stability. The temperature coefficient of the material is positive.
There is a scientific principle that ensures the economic viability of the global merchant market for raw materials consumed in capacitors: capacitance is directly proportional to the physical size of the finished capacitor, which can also be interpreted as “available surface area.” Therefore, capacitors are a raw material intensive industry.
New polymer materials are therefore required to overcome these temperature limitations. Accordingly, a new class of engineering materials, EPN (Ethylene-Propylene-Norbornene), has been developed for capacitor films, combining the advantages of polypropylene and cyclic olefin copolymers.
Polymers in Film Capacitors - The Next Generation Material is available! Polypropylene is the polymer of choice for most film capacitors, but there is an inherent high temperature limit for its usage. New polymer materials are therefore required to overcome these temperature limitations.
Aluminum capacitors require a variety of raw materials in their construction, including etched anode foil, etched cathode foil, separator paper (usually Kraft-Type or manilla paper), and electrolytes (typically, ethyl glycol).
Metallized films for capacitors and metallized film capacitors
However, the disadvantages of isolated safety film capacitors are also very obvious. From the principle point of view, the safety film capacitor is used to isolate the self-healing area to ensure safety. After long-term use, the capacity attenuation of the capacitor is greater than that of general metallized film capacitors.

Film capacitor
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:
