Abstract
An EMC filter circuit (1) has an essentially rigid busbar (3) for carrying an electric power to which is superposed a noise component in a conductive housing (2), which connected to ground. The filter (1) has two main elements inductors (4) increasing an impedance of the bus bar and capacitors (5) connected between the busbar (3) and the conductive housing (2). The capacitors (5) are inserted and tightly held solderless in position between the conductive housing (2) and the electric conductor (3). One advantage comes from the fact, that flat connection elements are arranged on both sides of the capacitors (5), which allow an easy manufacturing process.
