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.

Abstract: Presented herein is a modular connector with electromagnetic interference suppression. The modular connector includes a substrate, at least one set of spring pins, and a ferrite component. Each spring in the at least one set of springs includes a first portion adjacent the substrate and a second portion extending away from the substrate. The ferrite component surrounds the at least one set of spring pins, couples the at least one set of spring pins to the substrate, and is configured to suppress electromagnetic interference.
