Wound, solid state inductor

Abstract

Wound, solid state inductors are provided by winding flexible plastic tape having electrically insulative and magnetic permeability properties. Such tape is sometimes referred to as magnetic tape. An electrically conductive layer is placed on at least one surface of the magnetic tape, or both, and electrical connections are provided to the ends of the electrically conductive layer or layers. When the magnetic tape is wound into a coil, spirally or helically, and an alternating current is applied to the electrical connection, an inductive reactance will be noted. If there are two electrically conductive layers, and a voltage is applied between them, a capacitive reactance will be noted. In that case, a complex capacitive inductor element or inductive capacitor element has been configured. The wound inductors are small, light weight, inexpensive, and relatively shock proof, when compared with prior wound inductors having separate magnetic cones and wire windings placed over them. In an alternative embodiment, a single strip, or a pair of strips, of electrically conductive material may be formed by placing a plurality of diagonally oriented strips of conductive material on both sides of the flexible plastic tape, and connecting the portions where they overlie each other at each edge of the tape so as to provide an electrically conductive strip or strips having a length or lengths longer than the length of the tape.
