Abstract

A small-size patch common-mode inductor is disclosed in the invention and comprises a lower ceramic shell, an upper ceramic shell and a framework, an inner cavity groove is formed in the top of the lower ceramic shell, the framework is installed in the inner cavity groove in an embedded mode, and a coil is wound around the framework; the upper ceramic shell is fixedly installed at the top of the lower ceramic shell, an embedded column is arranged at the bottom of the upper ceramic shell, the bottom of the upper ceramic shell and the periphery of the embedded column are fixedly wrapped with first heat dissipation silica gel sheets, and second heat dissipation silica gel sheets are fixedly laid on the top of the lower ceramic shell and the groove wall of the inner cavity groove; and the bottom of the lower ceramic shell and the top of the upper ceramic shell are each provided with a plurality of evenly-distributed cooling fins. The beneficial effects of the inductor are that the sealing effect is good, the heat dissipation effect is good, and the heat dissipation area is greatly improved.

Description

technical field [0001] The present application relates to the field of inductors, in particular to a small-volume patch common-mode inductor. Background technique [0002] An inductor is a component that can convert electrical energy into magnetic energy and store it; the structure of an inductor is similar to a transformer, but it has only one winding; the inductor has a certain inductance, it only hinders the change of current; In the state, when the circuit is turned on, it will try to prevent the current from flowing through it; if the inductor is in the state of passing current, it will try to maintain the current when the circuit is turned off. Inductors are also called chokes, reactors, and dynamic reactors. [0003] The small-volume SMD common-mode inductors in the prior art are installed on the circuit board through the connecting column and used. They have the characteristics of small size, but due to the small size, it is not easy to install a heat dissipation st...
