Abstract:
1. A filter adapted to be mounted to a substrate and comprising: a core of dielectric material including a top surface with a first pattern of areas of conductive material, first and second opposed side surfaces, and third and fourth opposed side surfaces extending between the ends of the first and second opposed side surfaces respectively; a plurality of through-holes extending through the core and defining a plurality of respective openings in the top surface, the first pattern of areas of conductive material on the top surface surrounding at least a portion of one or more of the plurality of openings in the top surface; at least first and second walls protruding outwardly from the top surface, each of the first and second walls including an inner surface, an outer surface, and a top rim, the first and second walls defining respective first and second shields which prevent external electromagnetic fields from causing noise and interference; a first conductive input/output electrode on the first wall and in contact with the first pattern of areas of conductive material on the top surface of the core; a second conductive input/output electrode on the first or second wall; a first filter defined in part by the first pattern of areas of conductive material on the top surface of the core; and a second filter defined on one or more of the first to fourth side surfaces of the core, the filter being seated against the substrate in a relationship with the to rim of the first and second walls of the filter seated against a surface of the substrate, the top surface of the core of the filter facing and opposite the a surface of substrate, and the plurality of through-holes of the filter oriented in a relationship generally normal to the a surface of substrate.
