Abstract
An inductor core device, and method of forming same, that has at least a first inductor core section and typically has a second inductor core section, both formed of stacked layers of conductive material. The second core section may be positioned relative to the first core section to define an air gap therebetween and the sections are preferably profiled between their respective end faces and broad surfaces to reduce the eddy current losses induced in the core section(s) near the air gap. Various embodiments, “profile” shaping configurations, and core section arrangements are disclosed.
