Film capacitors use a thin plastic film as the dielectric that separates multiple metal electrodes. The electrodes are either deposited directly on the film (metallization) or are built from separate metal foils. The plastic metal sandwich is wound on a bobbin, and a terminal contact layer is deposited to connect all of the individual capacitor layers in parallel effectively.

Because paper is porous it has to be impregnated in order to prevent corona effects and flash-overs. It is done by use of melted wax or different kinds of oils, among other things mineral and silicone oils. The oils increase the tensional stability but decrease to a certain extent the εr. A fibrous paper has a εr ≈ 6.6 and the mineral oil ≈ 2.3 which gives the impregnated winding a εr varying between 3.1 and 4.5. The differences depend above all on the winding pressure produced by the tensile force during winding.

The double-stage filter family is therefore also appropriate for applications with particularly high EMC emissions, as is frequently encountered in industry. Typical applications include machines and systems for automatic production, motor drives and industrial plant machinery. These powerful filters are also the first choice for modern frequency inverters for motor control.
