Abstract
A magnetic device comprising a T-shaped magnetic core made of a material comprising a soft magnetic metal material and having a base and a pillar integrally formed with the base; a coil wound on the pillar; and a unitary magnetic body encapsulating the pillar, the coil and a portion of the base with a bottom surface of the base being not covered by the unitary magnetic body, wherein a contiguous portion of the unitary magnetic body encapsulates a top surface of the pillar and extends into a gap between a side surface of the pillar and an inner surface of the coil, wherein the core loss P(mW/cm) of the unitary magnetic body satisfies: 2×f×Bm≤P≤14.03×f×B, where f(kHz) represents a frequency of a magnetic field applied to the T-shaped magnetic core, and B(kGauss) represents the operating magnetic flux density of the magnetic field at the frequency.
