Abstract: A stacked transformer or inductor apparatus including a first layer with a first layer wire element extending around a center axis and a second layer with a second layer wire element. The second layer element includes side by side first and second wire components in parallel spaced relation extending around the center axis and the first wire component is connected to the first layer wire element to form a primary turn winding. A third layer includes a third layer wire element extending around the center axis and connected to the second wire component of the second layer wire element to form a secondary turn winding partially overlapping with the primary turn winding.
