Dieser Kondensatortyp lässt sich noch in zwei weitere Kategorien unterscheiden: Folienkondensatoren und Metallfolienkondensatoren. CAPCOMP bietet hochwertige Folienkondensatoren sowohl von TECATE als auch von DEKI an.
Often, a distinction is made in this type of capacitor between film capacitors and metal foil capacitors. The following description gives a brief information about their technical features.
Film capacitors usually consist of two aluminum foil electrodes with plastic films as a dielectric. In order to ensure the necessary safety and reliability of a capacitor, it is necessary to use a sufficient layer thickness. Typical advantages that have relatively large film capacitors over smaller metallized capacitors are
In contrast to film capacitors which use aluminum foils as electrodes, the electrodes of metal film capacitors consist of a thin metal layer (about 0.03 micron thick) which is vacuum deposited on the dielectric film. The connection of metallized capacitors takes place by means of a metal spraying process and by welding the leads to the sprayed ends. The main advantages of metallized capacitors are
