Metallized Film Capacitor Structure

EPCOS FK capacitors are produced using either winding methods or stacking methods. In the conventional production process, capacitors are made by individually rolling the metallized films or the film/foils into cylindrical rolls and then covering them with an insulating sleeve or coat-ing.

What is a metalized film capacitor?

General structure of metalized film capacitors. Metalized film capacitors are commonly used components in power electronics applications and their characteristics are drastically dependent on their operating frequency. Parasitic parameters could appear at low and high frequencies and disturb substantially the behavior of the component.

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 are plastic film capacitors?

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.

What are the electrical characteristics of a film capacitor?

In this standard, the electrical characteristics of capacitors are described by an idealized series-equivalent circuit with electrical components which model all ohmic losses, capacitive and inductive parameters of a film capacitor:

How are thin film capacitors made?

... However, all thin film capacitors share a common internal structure. In fact, they are constructed by coating the plastic films with zinc or aluminum and wrapping these metalized films on a cylindrical insulated base , .
