ABSTRACT:
A wire-wound inductor includes a dielectric core, terminals including wire staples that are crimped around the core, and a wire winding disposed about the perimeter of the core and connected to the terminals. A coating such as an adhesive coating is disposed over the wire winding and between the terminals. The process for manufacturing the inductors in a continuous process. Beginning with a spooled material, which may be extruded, inductors are formed on a core material sequentially. The inductors are not physically separated until the final stages of manufacturing, which is in contrast to the prior art method in which each inductor is individually constructed on an individual core that has been manufactured with tight tolerances and wound individually. By virtue of the characteristics of the inductor components, extremely tight tolerances (typically about 0.0005") can be obtained, resulting in highly controlled inductance values.
