Abstract: With an electrical device with a circuit arranged on a support plate and with a leadframe, forming electrical leads, for the electrical connection of the circuit to further electrical components, the support plate is in heat-conducting connection with at least a part of the leadframe. The leadframe may be formed at least partly with a flat surface area and the support plate may rest on the flat part. An electrical insulation between the support plate and the leadframe may be formed by a double-sided adhesive film or by a printed-on adhesive.

Abstract: In the case of an electrical device with a circuit arranged on a support plate and with a leadframe, forming electrical leads, for the electrical connection of the circuit to further electrical components, it is provided that the support plate is in heat-conducting connection with at least a part of the leadframe. In this case, the leadframe may be formed at least partly with a flat surface area and the support plate may rest on the flat part. An electrical insulation between the support plate and the leadframe may be formed by a double-sided adhesive film or by a printed-on adhesive.

Abstract: The invention relates to A compact electrical device, especially a switched-mode power supply, comprising a transformer for matching different electrical voltages, and an electrical circuit and a plug-in device, which can be connected to a reference voltage, at least one primary winding of the transformer being connected to the plug-in device and at least one secondary winding of the transformer being connected to the electrical circuit via conductor tracks, the primary and secondary windings enclosing at least a part of a transformer core.
