Abstract
An inductive electrical device comprises multiple laminations, each lamination comprising: a generally planar electrically nonconductive substrate that has a central axis normal to its plane, a first surface and a second surface; at least one electrically conductive layer pattern along the first surface in the form of a narrow strip that starts from a first point displaced from the central axis and extends along the first surface about the central axis through a first angle of rotation to a second point; a least one electrically conductive layer pattern along the second surface in the form of a narrow strip that starts from the second point and extends along the second surface about the central axis through a second angle of rotation to at least the first point; an electrically conductive coupling region passing through the substrate proximate the second point that couples the electrically conductive layer pattern along the first surface to the electrically conductive layer pattern along the second surface; wherein stacking the laminations upon each other form at least one winding with multiple turns for the inductive device.
