Circuit member with enhanced performance
An electrical connector includes a dielectric housing with a plurality of filtering modules therein. Each filtering module has a housing and a magnetics assembly including transformer cores with wires wrapped therearound. An array of pins extend from the module housing for connection to the wires. A plurality of tails extend from the module housing for interconnection to a circuit board upon which the connector may be mounted. An interconnection is provided between the pins and tails that may include filtering or other signal modifying circuitry. A circuit member having an enhanced layout is also provided for use in or upon which the connector may be mounted.
