Abstract
The utility model relates to a polymer composite plastic inductance which comprises a die-casting magnetic assembly. The polymer composite plastic inductance is characterized in that a coil assembly is arranged on the die-casting magnetic assembly to form a core body and comprises a coil body. Meanwhile, electrode sheets are distributed at the end of the coil body, and polymer magnetic plastic composite material layers are distributed on the periphery of the core body. Therefore, an integrated inductance is formed by means of matching of the die-casting magnetic assembly, the coil body, the electrode sheets and the polymer magnetic plastic composite material layers, and the convenient and fast degree of manufacturing is improved. Moreover, the polymer composite plastic inductance relies on the die-casting magnetic assembly, the magnetic permeability can be improved by 5%-35% or more, and the number of the coil is reduced so that the RDC value can be reduced by 5%-30% or more. Due to the fact that the polymer magnetic plastic composite material layers are applied, eddy current loss can be reduced, efficacy of the inductance on a printed circuit board (PCB) line can be improved, and meanwhile, the temperature of the inductance can be reduced when loading work is conducted on the inductance.
