What is a film capacitor?
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.
What are metallized film capacitors?
Like all capacitors, metallized film capacitors incorporate metal plates separated by a dielectric. 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.
Which polymer is best for film capacitors?
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.
How is a capacitor made?
The film of this capacitor is made with a very thin film drawing process. When the film is designed, then it may be metalized based on the capacitor properties. After that, electrodes are added to it and it can be arranged into a case. So that it can be protected from environmental factors.
Which film material is used in the production of Vishay film capacitors?
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.
What are the different types of plastic film capacitors?
There are two different types of plastic film capacitors, made with two different electrode configurations: Film/foil capacitors or metal foil capacitors are made with two plastic films as the dielectric. Each is layered with a thin metal foil, usually aluminum, as the electrodes.
