Film capacitors undergo self-heating due to ripple current and alternating current loss. When considering film capacitor specifications, it is important to take both the environment temperature and current conditions into consideration, and ensure that the design does not allow the element center temperature to exceed the heat-resistant temperature of the film.

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. The
