Title: Radio interference suppression choke

Abstract: A choke for suppressing radio interference, having a terminal wire composed of an electrically conductive and thermally conductive, non-ferromagnetic, first alloy and having a magnetic tape core composed of a ferromagnetic, second alloy. The magnetic tape core includes a thin band wound into a coil around the terminal wire that has one end positively connected to the terminal wire. In addition, an optimum thermal contact of the magnetic tape core with a printed circuit board via the terminal wire implemented as current-carrying conductor is achieved by the to choke. As a result, an excess temperature occurring in the magnetic tape core can be reduced to values compatible for the alloys employed. In this way, the problem of aging, which depends functionally on the temperature, can be dramatically minimized.
