ABSTRACT:
An inductor comprising one or more windings disposed on opposed first and second surfaces of a flat-plate substrate. The windings are applied to the substrate by plating or photoresistive deposition techniques, with through-holes through the plate accommodating the windings from opposed surfaces. Windings of more than one layer are obtainable with insulation between adjacent layers. The resulting inductor is usable, for example, as a component of an EMI filter in a power converter circuit.
