Abstract
Certain aspects of the present disclosure provide techniques and apparatus employing an isolation ring having a center strip of conductive material used to isolate magnetic fields generated by common-mode and differential-mode current flow through one or more inductors disposed in the ring. The apparatus generally includes an electrical component having an inductive element and a ring of electrically conductive material encircling the inductive element, wherein the ring has a strip of electrically conductive material disposed in the ring and connecting a first point on the ring to a second point on the ring.
