Abstract: The present invention is a component carrier (132) comprising of a plate of insulating material having a plurality of apertures (140) for accepting the leads of a thru-hole differential and common mode filter (130). Another embodiment comprises of a surface mount component carrier (10) comprising a disk (16) of insulating material having a plurality of apertures (24). The same concept for the above described carrier is also incorporated into several alternate embodiments, either independently, embedded within electronic connectors. The overall configuration and electrical characteristics of the concepts underlying the present inventions are also described as an energy conditioning circuit assembly which encompasses the combination of differential and common mode filters and component carriers optimized for such filters.
