Abstract:

A low profile electronic component in accordance with the invention includes an elongated core made from a magnetic material such as ferrite, which is connected to a base having a plurality of metalized pads attached thereto for electrically and mechanically connecting the component to a printed circuit board. Support structures or spacers are positioned at the ends of the core and are provided to assist the core in shielding the component and concentrating its magnetic lines of flux. The component also includes a winding of wire wound about at least a portion of the base and core assembly between the supports, and has the ends of the wire electrically and mechanically connected to the metalized pads of the base. A top portion may be coupled to the core via the supports to cover at least a portion of the windings of wire of the component. The supports separate the core and the top portion and maintain the top portion at a desired position with respect to the winding and the core.
