Abstract: The invention is directed towards a power source interface module for electronic circuits supplied by power from a power source as well as a power supply arrangement for electronic circuits comprising such a power source interface module. The module comprises a first circuit board carrying components, the first circuit board comprising a number of stacked circuit board layers as well as at least two openings, at least a part of a filter comprising at least one pair of magnetically coupled inductive coils, a core with two core legs, each core leg stretching through a corresponding opening in the circuit board, wherein each coil is wound around a corresponding core leg, the turns of the coils stretch through the circuit board layers, and each layer between an upper outer layer and a lower outer layer comprises at least a part of one turn.

Abstract: The present invention relates to a cover element, such as a lid for a module, such as a DC/DC-module and then preferably for a DC/DC-module of the so-called BGA-type. To enable manufacture and handling of DC/DC-modules to be simplified, the modules have been provided with a lid (2). The main purposes of a module lid is to provide a surface which enables the module to be vacuum-plucked and which provides a surface for marking the module and also which provides a certain degree of mechanical protection to the module printed circuit board (1) when handling the module. The lid has partially open sides (5) which enable cool air to pass around the components on the module and which also enable washing and rinsing liquids to be evacuated from the module.
