Patent ID: 7265531

Claim:
A current sensor comprising: a conductor having a narrowed region, a tab, and an intermediate region extending from the narrowed region to the tab, wherein the narrowed region has opposing, substantially planar surfaces, wherein the intermediate region has opposing, substantially planar surfaces, wherein the opposing, substantially planar surfaces of the intermediate region are generally parallel to the opposing, substantially planar surfaces of the narrowed region, wherein the narrowed region comprises a notch in a first side of the narrowed region, wherein the tab is adapted to couple to a circuit board with the opposing, substantially planar surfaces of the narrowed region substantially parallel to the circuit board; a magnetic field transducer; and a magnetic core having a central region and a pair of substantially parallel legs extending from said central region, wherein a selected one of said magnetic field transducer or said central region of the magnetic core is disposed in the notch and wherein the other one of the magnetic field transducer or the central region of the magnetic core is adjacent to a second, opposite, side of the narrowed region so that said pair of legs straddles the opposing, substantially planar surfaces of the narrowed region with each leg covering at least a portion of a respective surface of the magnetic field transducer.
