An electrical connector assembly comprising:

• an insulative housing forming a mating cavity communicating forwardly with an exterior along a front-to-back direction;
• a plurality of mating contacts disposed in the housing, each of said mating contacts including a front mating portion extending forwardly and upwardly into the mating cavity in a vertical direction perpendicular to said front-to-back direction, and a rear connecting portion extending downwardly;
• an insulative carrier located behind the housing and defining a receiving chamber;
• a small printed circuit board secured on a bottom face of the carrier, said connecting portions connected to a front region of said small printed circuit board, a plurality electronic components mounted upon the printed circuit board;
• a plurality of mounting contacts secured to a rear side of the carrier;
• and
• a set of magnetic components essentially received within the receiving chamber, each of said magnetic component including a magnetic core and a plurality of conductive wires;
• wherein
• each of said wires includes a front end mechanically and electrically connected to the rear connecting portion of the corresponding contact, and a rear end mechanically and electrically connected to the corresponding mounting contact.
