Abstract
A filtered coaxial connector is provided including an insulated housing, a conductive connector shell concentrically surrounding a center conductor, a ferrite cylinder concentrically located around a portion of the conductive shell and a leadless chip capacitor, one contact of which is electrically connected to the conductive shell. A solid metal washer is electrically connected with the second contact of the chip capacitor. When installed in an enclosure, the metal washer is additionally in contact with the enclosure panel, connecting the capacitor between the connector shell and the enclosure panel. Electrically, the ferrite cylinder is connected in series with the capacitor, thus forming an impedance divider. Common-mode noise generated within the enclosure is applied to this impedance divider, and is shunted through the capacitor to the chassis. As such, common-mode noise generated within the enclosure is attenuated before being permitted to spread throughout the network, via an attached coaxial cable.
