Abstract: A protective device including a substrate, a conductive section and a bridge element is provided. The conductive section is supported by the substrate, wherein the conductive section comprises a metal element electrically connected between first and second electrodes. The metal element serves as a sacrificial structure having a melting point lower than that of the first and second electrodes. The bridge element spans across the metal element in a direction across direction of current flow in the metal element, wherein the bridge element facilitates breaking of the metal element upon melting.

Abstract: A magnetic device includes a T-shaped magnetic core, a wire coil and a magnetic body. The T-shaped magnetic core includes a base and a pillar, and is made of an annealed soft magnetic metal material, a core loss PCL (mW/cm3) of the T-shaped magnetic core satisfying: 0.64×f0.95×Bm2.20≦PCL≦7.26×f1.41×Bm1.08, where f (kHz) represents a frequency of a magnetic field applied to the T-shaped magnetic core, and Bm (kGauss) represents the operating magnetic flux density of the magnetic field at the frequency. The magnetic body fully covers the pillar, any part of the base that is located above the bottom surface of the base, and any part of the wire coil that is located directly above the top surface of the base.
