Film capacitors with a double-sided metallized film effectively have thicker electrodes for higher surge current handling, but still do retain their self-healing properties, in contrast to the film/foil capacitors.
Healing — The windings which are now electrically connected by the schoopage have to be "healed". This is done by applying a precisely calibrated voltage across the electrodes of the winding so that any existing defects will be "burned away" (see also "self-healing" below).
Class 1 PP film capacitors are able to handle higher current than stability Class 1 ceramic capacitors. The precise negative temperature characteristics of polypropylene make PP capacitors useful to compensate for temperature-induced changes in other components.

Modern electronic ballasts usually change the frequency of the power from a standard mains frequency of 50 or 60 Hz up to quarenta kHz or higher, often using a Switched Mode Power Supply (SMPS) circuit topology with PFC. First the AC input power is rectified to DC, and then it is chopped at a high frequency to improve the power factor.

The electrode layers are wound slightly offset from each other, so that the edges of the electrodes can be contacted using a face contacting method "schoopage" at the collateral end faces of the winding. This internal connection is ultimately made by multiple point-shaped contacts at the edge of the electrode, and can be modeled as a large number of individual capacitors all connected in parallel.
For thicknesses greater than about 5 mils, the breakdown voltage only increases approximately with the square-root of the film thickness. On the other hand, the capacitance decreases linearly with increased film thickness. For reasons of availability, storage and existing processing capabilities, it is desirable to achieve higher breakdown voltages while using existing available film materials. This can be achieved by a one-sided partial metallization of the insulating films in such a manner that an internal series connection of capacitors is produced. By using this series connection technique, the Completa breakdown voltage of the capacitor can be multiplied by an arbitrary factor, but the total capacitance is also reduced by the same factor.

In general, film capacitors are not polarized, so the two terminals are interchangeable. There are two different types of plastic film capacitors, made with two different electrode configurations:
This property of self-healing allows the use of a single-layer winding of metallized films without any website additional protection against defects, and thereby leads to a reduction in the amount of the physical space required to achieve a given performance specification. In other words, the so-called "volumetric efficiency" of the capacitor is increased.
The dielectric films, depending on the desired dielectric strength, are drawn in a special process to an extremely thin thickness, and are then provided with electrodes. The electrodes of film capacitors may be metallized aluminum or zinc applied directly to the surface of the plastic film, or a separate metallic foil. Two of these conductive layers are wound into a cylinder shaped winding, usually flattened to reduce mounting space requirements on a printed circuit board, or layered as multiple single layers stacked together, to form a capacitor body.

This technique is analogous to get more info the "T metallization" technique described above, but operating at a larger physical scale. More-complex series and parallel arrangements of capacitor banks are also used to allow continuity of service despite individual capacitor failures at this larger scale.[15] Internal structure to increase voltage ratings[edit]
