Film Capacitors

The initial stage of manufacturing a film capacitor is to start with plastic film, or paper and film, and roll it up with thin aluminium or copper foil. As the film may contain microscopic flaws (and the paper always does), multiple layers of thin film is required rather than 1 layer of a thicker film.

Finding the Outside Foil Lead | Nuts & Volts Magazine

After some thought and research, I settled on metallized polyester film capacitors rated at 630 volts. I chose 0.0047 µF to replace the 0.005 µF waxies, 0.047 µF in place of the 0.05 µF ones, and 0.022 µF in place of the lone 0.02 µF capacitor used. ... so it was impossible to determine the outside foil on one capacitor and then assume ...
