ABSTRACT:
In accordance with the invention, an EMI suppressing connector comprises a body of ferrite having a plurality of conductive channels and at least one planar surface. The channel walls are wholly or partially coated with conductive material which provides a conductive path extending through the body and the planar surface includes a pattern of coated conductive leads connected to the conductive channels. Preferably the connector is in the form of a rectangular parallelopiped, and the channels extend perpendicularly between two major surfaces. In one embodiment, the conductive material extends horizontally through the body and onto planar bottom. The conductive material on the planar bottom surface provides ready connection with contacts on a circuit board or IC package. In another embodiment, the conductive material extends vertically through the body and onto a planar bottom or top. The conductive material on the planar surface can be configured in any desired pattern to define fanouts or mappings from one set of contacts to another.
