Patent ID: 6933805

Claim:
A device for filtering noise in a printed circuit board, comprising: a multiple layer circuit board having a plurality of conductive traces, wherein at least a first plurality of said conductive traces are located within a first plane; a first capacitive element, wherein said first capacitive element includes a dielectric interposed between a first conductive end and a second conductive end, wherein said first circuit element is oriented such that said first conductive end is proximate to said first plane and interconnected to a first conductive trace included in said first plurality of conductive traces and such that said second conductive end is distal from said first plane; a second capacitive element, wherein said second capacitive element includes a dielectric interposed between a first conductive end and a second conductive end, wherein said second circuit element is oriented such that said first conductive end is proximate to said first plane and interconnected to a second conductive trace included in said first plurality of conductive traces and such that said second conductive end is distal from said first plane; and a conductive shield, wherein said conductive shield substantially encloses a volume adjacent said circuit board and including said first and second capacitive elements, wherein said second ends of each of said first and second capacitive elements are electrically interconnected to said conductive shield, and wherein said conductive shield is electrically interconnected to a ground plane of said printed circuit board.
