An electrical device for mounting on a circuit board, such as an inductor or a transformer. The device contains first and second core halves which can be mated to one another. Each half contains an outer skirt attached to a back-plane, and a center core component which is attached to the back-plane in a position which is perpendicular to the back-plane and to the circuit board, when mounted. The center core component has a primary axis and a secondary axis, the secondary axis having a smaller dimension than the primary axis, and a cross-section with a ratio of length of primary axis to length of secondary axis of 1.1:1 to 3.5:1. The outer skirt, back-plane, and center core component all contain magnetic material, e.g. ferrite. A bobbin having a hollow center section with a cross-section of similar shape to the cross-section of the center core components is attached to first and second flanges, each of which flanges has wire mounting posts on its bottom edge. At least one coil is wound around the exterior surface of the bobbin. When the first and second core halves are mated, the center core components are inserted into the center section of the bobbin to form a magnetic core. The coil is attached to at least one pair of wire mounting posts to allow electrical connection to the circuit board.
