摘要:
The present invention relates to an electrical device comprising a first electrical module, a second electrical module, a flexible conductor foil including a plurality of electrical conductors electrically connecting the first and second electrical module with each other, and a filtering element (3). In order to achieve improved electromagnetic filtering, while guaranteeing reasonable manufacturing costs, the filtering element (3) is mechanically integrated in the electrical device and the flexible conductor foil is at least partially led through the filtering element (3), thereby electromagnetically filtering the plurality of electrical conductors.
