Knowledge Base

Although the behaviors and characteristics of the different types of capacitors are taught at universities, passive components often do not enjoy the same attention as e.g. active components. At the same time, they substantially influence the behavior of the circuits in which they are used. In our knowledge base, we try to counter this and provide you with in-depth knowledge on film capacitors and their application possibilities.

Basic technical data of capacitors

In this section the basic principle of the capacitor is explained and basic knowledge about the dielectric and the electrical values such as capacitance, voltage, tolerance, derating, insulation resistance and loss factor/ESR is given.

Construction principles of film capacitors

Film capacitors are generally produced either in pulse-resistant film/foil technology or as a metallized self-healing version. However, there are constructions in which the advantages of both types of construction are combined.

More Information

Dielectrics

The dielectric is the insulator which is located between the current-carrying electrodes. In the case of film capacitors, various plastic films are used, the properties of which are decisive for the behavior of the capacitors.

Special Technical Subjects

In this section, the advantages of plastic film technology compared to other types of capacitors are explained and processing and application recommendations are given especially for our WIMA capacitors.
