Abstract: A network jack includes a connector, an outer housing, and a circuit board. The connector receives a plug for conveying Ethernet network signals. The connector includes conductive leads disposed on opposite sides of a central bar. The connector has a connector housing formed in part by a plurality of walls defining an interior, wherein the central bar is disposed in the interior, and spaced part from each of plurality of walls. The outer housing is disposed about and contains the connector housing, and has a width approximately equal to a width of a housing of the plug. The circuit board is disposed within the housing, and supports a plurality of transformers and/or common-mode chokes. The circuit board provides at least a portion of an electrical connection between the conductive leads and the transformers and/or common mode chokes.
