Film capacitors' dielectric materials and their market share

Characteristics of film materials for film capacitors

The electrical characteristics, and the temperature and frequency behavior of film capacitors are essentially determined by the type of material that forms the dielectric of the capacitor. The following table lists the most important characteristics of the principal plastic film materials in use today. Characteristics of mixed film materials are not listed here.

The figures in this table are extracted from specifications published by various different manufacturers of film capacitors for industrial electronic applications. ^{[25] [26] [27] [28] [29] [30][31]}

The large range of values for the dissipation factor includes both typical and maximum specifications from data sheets of the various manufacturers. Typical electrical values for power and large AC capacitors were not included in this table.
