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.
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.
Although the materials and construction techniques used for large power film capacitors are very similar to those used for ordinary film capacitors, capacitors with high to very high power ratings for applications in power systems and electrical installations are often classified separately, for historical reasons.
Film capacitors are widely used in power electronics applications including but not limited to DC Link, DC output fltering, and as IGBT snubbers.
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.
Metallized film capacitors are made of two metallized films with plastic film as the dielectric. A very thin (~ 0.03 μm ) vacuum-deposited aluminum metallization is applied to one or both sides to serve as electrodes.
