Abstract: A shield is described for minimizing leakage of electromagnetic waves from a connector/chassis interface. The shield includes a conductive strip sized to at least partially surround an aperture in a chassis, where the chassis receives a connector port assembly through the aperture. The conductive strip includes an outer portion affixed to an interior surface of the chassis, and an inner portion able to be manipulated to at least partially cover one or more gaps between the connector port assembly and the chassis.

Abstract: In one embodiment, an apparatus includes an array of transformers and common mode chokes each comprising a magnetic core and windings wound around the magnetic core at opposing locations on the magnetic core, and a retaining groove on each of the magnetic cores to maintain the windings in their opposing locations on the magnetic core. The transformers and common mode chokes are positioned in the array with the windings on each of the magnetic cores located offset to the windings of adjacent magnetic cores in the array to reduce crosstalk and improve common mode noise rejection.

Abstract: An electrical device includes a core structure having a first core section, a second core section, and a third core section. The electrical device further includes a first coil electrically coupled to the first core section and the second core section to form a choke and a primary winding of a transformer. The choke is configured to reduce common mode noise for an electrical signal received by the electrical device, and the primary winding of the transformer is configured to induce a magnetic field on the third core section. The electrical device also includes a second coil electrically coupled to the third core section, which forms a secondary winding of the transformer and receives electromagnetic energy from the magnetic field induced by the primary winding of the transformer.
