The invention relates to a radio interference suppression choke, comprising a connection wire (1) consisting of an electroconductive and heat conductive non-ferromagnetic first alloy and a strip-wound magnetic core (2) consisting of a ferromagnetic second alloy and comprising a thin strip wound around the connection wire (1) to form a coil and connected to said connection wire (1) at the ends with a positive fit. In addition to enabling automatiseable further processing, the inventive radio interference suppression choke provides optimal thermal contact of the strip-wound magnetic core with the printed circuit board via the connection wire which is configured as a current-carrying conductor. This enables any excess temperature arising in the strip-wound magnetic core to be reduced to a more suitable level for the alloys used and consequently drastically reduces the problem of ageing which is e-functionally related to temperature.
