Abstract

The interference suppression coil has a magnetic core (1) carrying at least two windings (3) with a high symmetrical inductance component for damping symmetrical and unsymmetrical interference currents. The individual windings (3) are fitted with external cores (2) on the outside of the magnetic core (1), exhibiting a high magnetic saturation. Pref. the magnetic core (1) comprises a number of individual annular ferrite cores (6) combined together, the individual windings (3) made from an insulated copper conductor fitted with a cylindrical or U-shaped core on the outside of the magnetic core (1).
