Film capacitors are a type of capacitor that uses a thin plastic film as its internal dielectric. Like paper capacitors, the film sheet can sometimes be metalized which can reduce the size of the capacitor. Film capacitors are commonly used as they have a low distortion factor along with good frequency characteristics.
A Film Capacitor can be chosen its film based on the requirement of stability and where the cost is concerned. A capacitor whose dielectric is chosen is of the ‘Film’ type. This type posses stable behavior, low manufacturing cost. These types of capacitors are defined as film capacitors.
In the modern type of film capacitor, there is the ‘direct electrical connection’ establishment with the electrodes that are present on both the winding’s. This keeps the path of the current to the electrode very short. This capacitor has various benefits like it has very low ESR (ohmic resistance) and ESL (Parasitic Inductance).
Film capacitors are manufactured by creating an extremely thin layer of film (under 1 µm) that requires a complicated film drawing process. The material of the film is chosen at the beginning and is sometimes coated with a metalized substance on one side.
This, in turn, increases the reliability of the capacitor Application of Metalized Film Capacitor: The metallic film capacitors are widely used in power electronic circuits including DC link circuits, pulse circuits, switching circuits, etc. The low power metalized film capacitor find their use in decoupling and filtering applications.
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.
