Abstract
With an ignition coil module comprising a coil system which includes a primary winding and a secondary winding and a flux conducting, soft magnetic device to increase and/or to conduct a magnetic flux generated by one of the windings and comprising an electronic component to control the coil system which has an electrical circuit and a heat sink to cool the electronic component, at least one section of the heat sink is connected to a section of the flux conducting device in a thermally conductive manner such that waste heat of the electronic component can be dissipated over the section of the flux conducting device.
