Power Film Capacitor Application Guide

the dielectric system vaporizes the metal deposit in the area of the fault, a process known as clearing. The result of "clearing" is a tiny amount of capacitance loss while allowing the capacitor to continue to operate without any adverse efects. If a condition arises that causes multiple clearings, such as overvoltage, or dielectric aging at end of life, the capacitor will continue to

How do metallised film capacitors work?

Unlike film capacitors, which use aluminium foils as electrodes, the electrodes of metallised film capacitors consist of a thin metal layer (about 0.03 microns thick) deposited on the dielectric film in a vacuum. Metallised capacitors are connected by a metal spraying process and by welding the leads to the sprayed ends.

The terminals are connected to the end-faces of the electrodes by means of welding or soldering.

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 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.

What is a segmented film technology capacitor?

On Segmented Film Technology Capacitors, the self healing effect is more controlled. The film metalization is made by forming a pattern of segments, which are connected to each other by micro fuses. This limits the healing current and limits the self-healing effect to a well defined section of the film.

What is the difference between film and foil capacitors?

In the case of film and foil types, the electrode is not applied as for the metallized capacitors, but is wound with the dielectric as a metal foil. Due to their lower series resistance, the components produced this way have excellent pulse and current carrying capability, as well as a very high insulation resistance.
