Abstract

A combination of a common-mode choke and two integrated RF inductors includes first and second E-core. At least one E-core includes first and second protrusions extending from a body portion. Each protrusion is configured to accommodate a respective winding. In a first embodiment, each protrusion extends from the body portion at an angle perpendicular to legs extending from the body portion. In a second embodiment, each protrusion extends from the body portion in an opposite direction from the legs extending from the body portion, and each protrusion includes a respective channel to receive a respective winding. In a third embodiment, each protrusion extends from the body portion in an opposite direction from the legs extending from the body portion, and each protrusion is sized and shaped to extend into a respective opening in a printed circuit board. Each opening is surrounded by a respective printed circuit winding.
