Abstract:

The patent describes a microminiature leadless inductance element having a closed magnetic loop. The inductance element comprises a conventional U-shaped ferromagnetic core having a wire winding around its center. Grooves are provided at the underside of the feet of the U-shaped core so as to receive the terminal portons of the wire winding. The grooves are coated with an electrical conductor and a similar electrically conductive coating is provided on the substrate such that an electrical connection is made without the use of soldering wires. A closed magnetic loop is achieved by applying a ferromagnetic coating along a portion of the substrate surface such that when the U-shaped core is placed on the substrate, all the flux lines generated within the core are conducted through the ferromagnetic coating on the substrate.
