An electrical configuration having at least one component which has at least one current bar, particularly a lead frame, and having an electronic circuit which has at least one heat dissipation surface and at least one electric terminal that is connected mechanically and electrically to the current bar. It is provided that the unit made up of the component and the electronic circuit is mounted on a support layer that effects the heat dissipation in such a way that, because of the fastening of the component onto the support layer, the heat dissipation surface is pushed against the support layer, based on the spring property of the current bar.
