Abstract: A lead frame for a current sensor is provided. The frame includes a conductive piece with an average thickness, and a sensing zone for generating a signal detectable by a current sensing element when current flows through the lead frame. It also includes a routing zone outside the sensing zone for routing current towards the sensing zone. The routing zone comprises a region with the largest area having a predetermined average thickness. At least the sensing zone includes additional material disposed on the conductive piece so the total thickness of the sensing zone is thicker than the average thickness of said largest area.
