AI Customer ServiceThe type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is evaporated on the plastic dielectric material. The thin metalized electrodes have a thickness of approximately 10 nm to 50 nm.
The thin metalized electrodes have a thickness of approximately 10 nm to 50 nm. The electrodes of film / foil capacitors have discrete metal foils with thicknesses of approximately 5 μm to 10 μm. Metalized capacitors have a self-healing behavior as an intrinsic characteristic. Self healing is the ability to recover after a dielectric breakdown.
Although for the film type capacitor, it’s just fine to connect positive or negative to the inner or outer foil. But due to some reason, it’s preferable to connect the outer foil to negative side or to the “nearest” negative side (input side on coupling application). Why? Because the outer foil will catch the outside interferences.
Due to their construction, very thick electrodes, film / foil capacitors can carry higher currents than metalized types, but are much larger in volume. These capacitors can not recover after a breakdown. Therefore In some constructions double side metalized plastic film is used as electrode to replace the foil.
If both the anode and cathode foils have an oxide film, the capacitors would be bipolar (non-pola) type capacitor. These technical notes refer to "non-solid" aluminum electrolytic construction in which the electrolytic paper is impregnated with liquid electrolyte.
Basically, most of the capacitor, has what we call the inner foil and outer foil. Because, most of capacitor’s construction is based on the winding of paper or other conductor (silver, copper, gold, etc), so we will have a start position (the inner foil) and the finish position (the outer foil).
