Patent ID: 8466766

Claim:
An inductor core device, comprising: a first inductor core section including alternating layers of conductive material and insulative material, each of the layers of conductive material having a broad surface and at least a first edge; a second inductor core section including layers of conductive material and insulative material, each of the layers of conductive material having a broad surface and at least a first edge, the second core section being positioned relative to the first core section to define an air gap therebetween; wherein each of the first and second core sections includes: an end face adjacent the air gap where the first edges of a majority of the conductive material layers terminate, a core section broad surface that includes the broad surface of an exteriorly disposed one of said conductive material layers, and a profiled transition region where the first edges of a minority of the conductive material layers terminate, the profiled transition region located between and separating the end face and the core section broad surface; wherein the profiled transition region extends from the end face to the core section broad surface in each core section.
