Patent ID: 7339451

Claim:
An inductor comprising: a coil formed from a conducting wire, the coil having (i) an upper side (e.g., 420 - 1 in FIG. 6D ) and a lower side (e.g., 420 - 2 ) defining height of the coil and (ii) two radii of curvature being an outer radius of curvature and an inner radius of curvature, wherein the conducting wire comprises: a first extension end (e.g., 425 - 1 ) located at the outer radius between the upper side and the lower side of the coil height; a first coil portion connected to the first extension end and defining a first curved transition (i) from the outer radius to the inner radius and (ii) from the location between the upper and lower sides of the coil height to the lower side of the coil height; a second coil portion connected to the first coil portion and defining, at the inner radius, a second curved transition from the lower side of the coil height to the upper side of the coil height; a third coil portion connected to the second coil portion and defining a third curved transition (i) from the inner radius to the outer radius and (ii) from the upper side of the coil height to a location between the upper and lower sides of the coil height; and a second extension end (e.g., 425 - 2 ) connected to the third coil portion and located at the outer radius between the upper and lower sides of the coil height; and magnetic bonding material molded within and around the coil.
