Abstract: A housing for electrical components that is suitable for mounting on printed circuit boards or other supporting members to be used in electrical-electronic equipment. The housing has a generally regular configuration (preferably rectangular), is enclosed on all sides, and preferably is fabricated from electrically conductive and ferromagnetic material. At least one surface of the housing (generally the bottom) has a plurality of housing supporting projections, preferably in the form of integral embossments, extending a predetermined distance for raising the housing above the surface of the printed circuit board or other supporting member a sufficient amount to provide for further processing or use such as to accommodate a cleaning or cooling flow of fluid. The projections are irregularly arrayed with respect to the sides of the housing and provide both tactile and visual indicators for facilitating proper alignment of the housing during placement on a printed circuit board or other supporting member. A plurality of electrically conductive leads extend through insulated openings in the bottom of the housing and are located at the intersections of an equally spaced grid system. The projections extending from the bottom of the housing are positioned so as to be located at selected spots corresponding to the intersections of the same equally spaced grid system that locates the electrically conductive leads. A greater number of the projections are formed on one side of the housing than are formed on the other in order to provide the irregularity in the array of projections required to facilitate alignment of the component during placement on a printed circuit board or other supporting member. Grounding strips of conductive material may be attached to the sides of the housing and where so attached, are so positioned relative to the intersections of the same equally spaced grid system locating the electrically conductive leads and projections as to fit into a logical extension of the equally spaced grid system. The sides of the housing may be hermetically sealed closed to provide a protective environment for the electrical components contained therein.
