Abstract

The invention discloses an inductor bar and a manufacturing method thereof, and the inductor bar comprises at least one magnetic core; at least two conductors arranged on the magnetic core, wherein each conductor comprises a base part and an electrode part, the surface of each base part is insulated, and the conductors are assembled with the magnetic core through the base parts; a magnetic plasticpackage layer arranged on the magnetic core and the conductors, wherein the magnetic core and the conductor are both located in the magnetic plastic package layer, the magnetic core and the conductorare attached to the magnetic plastic package layer, and an electrode part of the conductor penetrates through the magnetic plastic package layer to be communicated with the outside. No air gap existsbetween the inner magnetic medium and the outer magnetic medium of the inductor bar, so that a high inductance value can be maintained under the condition of high current, almost no noise is generated under high frequency, and the reliability is high.

Description

technical field [0001] The present application relates to the technical field of molding, in particular to an inductor bar and a manufacturing method thereof. Background technique [0002] Existing electronic products are gradually developing toward integration and functional diversification, and such development requires the support of electronic components such as miniaturization, thinning, and high reliability. [0003] Among them, the inductor is one of the above-mentioned electronic components, and the stable operation of the electronic circuit usually requires arranging multiple inductors in the electronic circuit to work together, or using an inductor row to work, and the inductor row is assembled on the magnetic core. A device with multiple conductors, and most of the conductors are terminals, multiple terminals cooperate with the magnetic core to achieve the effect of arranging multiple inductors. [0004] In electronic circuits, in order to improve the space utili...
