Abstract

The invention is suitable for the field of electronics, and provides an inductor and a manufacturing method thereof. The inductor comprises a ferrite substrate, a conductive coil arranged in the ferriThe invention is suitable for the field of electronics, and provides an inductor and a manufacturing method thereof. The inductor comprises a ferrite substrate, a conductive coil arranged in the ferrite substrate, and terminal electrodes which are positioned at two end parts of the ferrite substrate and used for electrically connecting with the conductive coil. The conductive coil comprises a plurte substrate, and terminal electrodes which are positioned at two end parts of the ferrite substrate and used for electrically connecting with the conductive coil. The conductive coil comprises a plurality of layers of electrode patterns which are connected layer upon layer spirally. The layers of the electrode patterns are electrically connected through electric connecting elements to form a spirality of layers of electrode patterns which are connected layer upon layer spirally. The layers of the electrode patterns are electrically connected through electric connecting elements to form a spiral ellipse-like shape. In the inductor provided by the invention, the conductive coil adopts an ellipse-like spiral structure so as to make the inductor realize the specific inductive characteristic aal ellipse-like shape. In the inductor provided by the invention, the conductive coil adopts an ellipse-like spiral structure so as to make the inductor realize the specific inductive characteristic and the impedance characteristic and integrates the inductor and beads into a whole.nd the impedance characteristic and integrates the inductor and beads into a whole.

Description

technical field [0001] The invention belongs to the field of electronic appliances, in particular to an inductor and a manufacturing method thereof. Background technique [0002] With the continuous development of electronic technology, especially the continuous reduction of volume, the requirements for inductors are getting higher and higher; The trend develops. Among them, chip type, miniaturization and integration develop most rapidly, while composite technology requires relatively high technology and develops relatively slowly. As chip, miniaturization, and integration technologies are approaching the technical limit, composite technology has to undertake the mission of further reducing the relative space occupancy rate of inductors. As one of the three major components of the inductor, its compounding is currently mainly in the chip filter. [0003] Inductors are divided into inductors and magnetic beads according to their application characteristics; among them, ind...
