Electric inductor with high-quality factor

The utility model discloses an electric inductor with high-quality factor. The electric inductor comprises a base bottom, an inner layer of electric inductor layer, a protective layer, the electric inductor layer of a top and the electric inductor layer of a welding zone. Wherein, a dielectric layer is covered with the surface of the base bottom, and the dielectric layer is provided with at least one dielectric layer opening. In addition, the inner layer of the electric inductor layer is arranged in the dielectric layer. The dielectric layer opening is filled with the electric inductor layer of the top, and the electric inductor layer of the top is electrically connected with the inner layer of the electric inductor. Besides, the protective layer is arranged on the surface of the dielectric layer, and the protective layer is provided with a protective layer opening which makes the electric inductor layer of the top be exposed. In addition, the protective layer opening is filled with the electric inductor layer of the welding zone, and the electric inductor layer of the welding zone is electrically connected with the electric inductor layer of the top. Part of the electric inductor is made in the dielectric layer, and the other part of the electric inductor is made on the welding zone of acomponent zone and made on the surface of the protective layer by the albronze alloy material. Thus, the utility model can greatly increase the electric inductor part in the dielectric layer and reduce the resistance value (Rs). Thus, the quality factor can be improved, and the frequency domain of application can be enlarged.
