摘要:
A surface-mountable magnetic device comprising: (1) a multi-layer circuit containing a plurality of windings disposed in layers thereof, the multi-layer circuit having first and second lateral recesses associated therewith, the first and second lateral recesses intersecting the layers of the multi-layer circuit, (2) a conductive substance disposed within the first and second lateral recesses and electrically coupling selected ones of the plurality of windings and (3) a magnetic core mounted proximate the plurality of windings, the magnetic core adapted to impart a desired magnetic property to the plurality of windings, the device locatable proximate a substantially planar substrate to allow the first and second lateral recesses to act as conductors between the plurality of windings and electrical conductors on the substantially planar substrate, the plurality of windings and the magnetic core substantially free of a surrounding molding material to allow the magnetic device to assume a smaller overall device volume.
