Disclosed is an emc - filter circuit (1) which are of a substantially rigid contact rail (3) for guiding of electrical current, of the of a noise component is superimposed, into a conductive housing (2), which is earthed. The filter (1) comprises two main inductors (4), which an impedance of the conductor rail is increased and capacitors (5) which, between the conductor rail (3) and the conductive housing (2) are connected. The invention is characterised in that the capacitors (5) attached by soldering a manner that between the conductive housing (2) and the electrical conductor (3) is inserted and are held firmly in position. An advantage is based on the fact that flat connection elements on both sides of the capacitor (5) are arranged, which makes possible a simple manufacturing process.
