Embodiment Construction

[0031] Embodiments of the present invention provide an inductor and a method for manufacturing the inductor, which are at least used to solve the technical problems in the prior art that the inductor has a large volume and weight and a narrow application range.

[0032] In order to solve the above technical problems, the technical solution idea provided by the present invention is as follows:

[0033] In the technical solution of the embodiment of the present invention, the inductor includes an enameled wire made by winding, and a cured film arranged on the surface of the enameled wire and used to fix the enameled wire. The enameled wire includes two lead ends. The enameled wire is fixed and supported, so that the inductance does not rely on the support of the magnetic core, thereby removing the magnetic core in the inductance, realizing an air-core inductance, and achieving the technical effect of reducing the volume and weight of the inductance; at the same time, due to the i...

Abstract

The invention relates to the technical field of electronics, in particular to an inductor and a method for manufacturing the same. The inductor comprises a wound varnished wire and an immobilizing membrane, wherein the varnished wire comprises two leading-out terminals, and the immobilizing membrane is arranged on the surface of the varnished wire and used for fixing the varnished wire. The inductor is at least used for solving the technical problems that in the prior art, an existing magnetic core magnetized inductor is large in size and weight and the application range is narrow.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an inductor and a method for manufacturing the inductor. Background technique [0002] Broadband inductors can be used in radio frequency, microwave, and millimeter wave integrated circuits, optical and electrical communication circuits, broadband amplifiers, broadband bias-tees (biasers), and broadband filters. [0003] Inductance in the prior art either winds the copper enameled wire on the surface of the magnetic core, or puts the conductor coil into the magnetic body. However, since the magnetic core or magnetic body has a certain volume and weight, the overall volume and weight of the inductor are relatively large. Moreover, both the magnetic core and the magnetic body are magnetic materials, which result in a strong magnetic field or limited use of non-magnetic materials, so the application range is narrow.
