Abstract
Abstract The housing protects a circuit comprising active power components 10, 11, 12. A power electrode of the component 10 is welded onto the flush surface 15 of a radiator 13 accommodated in the base of the housing. The radiator is formed in one piece with an elongate part 14, the end 5 of which projects from the housing in the form of an external connecting pin. The radiator 13 may take various forms, including that of a grid.
