Metallized-plastic film capacitor with a definite temperature coefficient and resisting ageing.

摘要

The invention relates to a foil capacitor of the type with definite temperature coefficient and good stability over time, consisting of a stack of dielectric elements separated by electrodes, the electrodes being connected by lateral electrical connections, the even ones to one another and the odd ones to one another. The dielectric elements comprise two different materials and the electrodes consist of metallisations (2,3) deposited on the opposite faces of one of the dielectrics (1) which is polypropylene or polyester, the stack being made in such a way that one electrode separates two dielectric layers of different kinds (1,10). <IMAGE>
