Abstract

The present invention is a surface mount component carrier comprised of a disk of insulating material having at least two apertures. The disk is substantially covered by a metalized ground surface and includes at least two conductive pads surrounding the apertures, and insulating bands which surround each conductive pad. The insulating bands separate and electrically isolates the conductive pads from the metalized ground surface. A surface mount component, such as a differential and common mode filter, is positioned lengthwise between the two conductive pads and operably coupled to the carrier. Once the surface mount component is coupled to the carrier, the combination can be manipulated, either manually or through various types of automated equipment, without subjecting the surface mount component to mechanical and physical stresses normally associated with the handling of miniature components. The carrier also provides the added benefit of improved shielding from electromagnetic interference and over voltage dissipation due to the surface area of the metalized ground surface. The same concept for the above described carrier is also incorporated into several alternate embodiments, either independently or embedded within electronic connectors.
