INDUCTOR, TRANSFORMER, AND METHOD

In accordance with an embodiment, a circuit element includes a flexible foldable substrate having portions of a first inductor formed on first and second major surfaces of the flexible substrate. In accordance with another embodiment, a first electrically conductive having a first terminal, a second terminal, and a first annular-shaped portion between the first terminal and the second terminal trace is formed on a first portion of the first major surface. A second electrically conductive trace having a first terminal, a second terminal, a first annular-shaped portion between the first terminal and the second terminal of the second electrically conductive trace, and a second annular-shaped portion between the first terminal and the second terminal of the second electrically conductive trace is formed on the second major surface. The first electrically conductive trace is coupled to the second electrically conductive trace by a thru-via.
