Island Metallized Film Capacitors

What are metallized capacitor films?

Metallized capacitor films have a thin coating of metal (commonly aluminium and zinc) deposited on them by vacuum deposition process. Several types and patterns are available to choose for metallization, depending on application and usage environment. This was the first metal used when metallized films were developed back in 1970s.

What are the advantages of metal-Lized polypropylene film capacitors?

Capacitors made from metal-lized polypropylene film display low dielectric losses, high insula-tion resistance, low dielectric ab-sorption, high dielectric strength and deliver a robust, space-efficient solution. Long-term stability is also good. These Figure 1

What is a metallized capacitor?

An M ( metallization) is prefixed to the short identification code of capacitors with metallized films. *) MFP and MFT capacitors are constructed using a combination of metal foils and metallized plastic films. They are not covered by DIN EN 60062:2005. The following table is a summary of important technical data.

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 is a thin film capacitor?

These capacitors are sometimes also called as a metalized capacitor or plastic capacitors. A Thin Film Capacitor is nothing but bipolar capacitors with plastic films as their dielectric. These films are either metalized or just placed in layers to form out a roll or a candy-like the rectangular shape.

What is a film/foil capacitor?

As the name suggests, the film/foil capacitor uses plastic films as dielectric and is placed inside two layers of electrodes made of aluminum foil. These interleaved layers are so structured that the metallic layers do not contact with each other. These capacitors can be either inductive or non-inductive.
