Patent ID: 7342477

Claim:
An Inductor comprising: a low-profile magnetically permeable substrate; a first set of windings magnetically coupled to the substrate and producing a first resultant magnetic field in response to an input signal applied to the first set of windings; a second set of windings magnetically coupled to the substrate and having a second magnetic field in response to an input signal applied to the second set of windings; the first and second sets of windings being disposed on the substrate in magnetically uncoupled relation with each other and such that the resultant fields are substantially mutually parallel; each set of windings comprises a first winding and a second winding in series with the first winding; and the first and second windings of each set are magnetically coupled to the substrate, so that the first winding and second winding each comprise a pair of inductors connected in series; and the inductance of the first winding of each set of windings is greater than the inductance of the second winding of each set, so that the impedance of the first winding is greater than the impedance of the second winding in response to an AC signal applied to the set of windings.
