Claim 0:
1. A magnetic device, comprising:
a T-shaped magnetic core, comprising a magnetic powder, wherein the T-shaped magnetic core comprises a base and a pillar, wherein the base comprises a top surface and a bottom surface opposite to the top surface, and the pillar is located on the top surface of the base;
a coil, wound on the pillar; and
a magnetic body, encapsulating the pillar and the coil, wherein the magnetic body and the bottom surface of the base form an outer surface of the magnetic device, wherein the magnetic body does not have any portion that is located below the bottom surface of the base of the T-shaped magnetic core, wherein a first portion of the magnetic body extending in a direction from the top surface to the bottom surface of the base of the T-shaped magnetic core is in contact with a first lateral surface of the base of the T-shaped magnetic, wherein an electrode is disposed on the bottom surface of the base of the T-shaped magnetic core and extends to a bottom surface of the first portion of the magnetic body, wherein a unitary and contiguous top surface of the electrode is in contact with a contiguous surface formed by the bottom surface of the base of the T-shaped magnetic core and the bottom surface of the first portion of the magnetic body;
wherein μC×Hsat(Oe)≥1800, where μC is a permeability of the T-shaped magnetic core, and Hsat(Oe) is a strength of the magnetic field at 80% of μC0, where μC0 is the permeability of the T-shaped magnetic core when the strength of the magnetic field is 0.
