Patent ID: 7598839

Claim:
A bobbinless inductive device, comprising; a plurality of winding elements, wherein each winding element further comprises a plurality of winding ends that can be terminated; at least three magnetically permeable and substantially identical and separable core elements, wherein said magnetically permeable core elements are disposed in a substantially co-axial coplanar arrangement with respect to an external substrate to which the inductive device is mounted an orthogonal magnetically permeable core element, said orthogonal magnetically permeable core element similar in shape to said at least three magnetically permeable and substantially identical core elements and disposed in a substantially orthogonal and coplanar arrangement with said at least three magnetically permeable and substantially identical core elements; and means for attaching said magnetically permeable core elements to one another; wherein said plurality of winding elements each reside at least partly inside respective cavities formed by said substantially co-axial magnetically permeable core elements and said orthogonal magnetically permeable core element.
