Abstract
The utility model discloses a common mode choke which comprises an annular magnetizer, wherein two groups of symmetrical coils are wound on the annular magnetizer, each group of coil is provided with an independent lead terminal, the lead terminals are arranged on two sides of the magnetizer, and two lead terminals of different coils on the same side of the magnetizer penetrate a panel connected with the magnetizer. The common mode choke can achieve high impedance and excellent frequency characteristic and large capacity.
Description
Technical field
The utility model relates to a kind of common mode inductance, belongs to the electric component field.
Background technology
In circuit engineering, especially Switching Power Supply needs to use common mode inductance to be used for filtering the electromagnetic interference signal of common mode, because the existence of common-mode signal, circuit signal is easy to generate negative effect, therefore need suppresses common-mode signal, improve the circuit electrical characteristic.Existing common mode inductance one section enamelled wire of coiling on iron core on the market, its impedance is low, and inductance value is low, and load is low, only can be used for limited occasion.
Summary of the invention
At the defective of prior art, the utility model discloses a kind of common mode inductance, can effectively suppress the generation of common-mode signal, its frequency characteristic is good, high impedance, high inductance, load height, has superior electric property.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of common mode inductance, comprise annular magnetizer, be surrounded with two groups of symmetrical coils at annular magnetizer, every group of coil all has the lead terminal that independently is positioned at the magnetic conductor both sides separately, and two lead terminals of the different coils of magnetic conductor the same side pass the flat board that links to each other with magnetic conductor.
Wherein, described flat board is made by ambroin.
By said structure, farthest reduced electromagnetic interference, improved impedance and inductance value; Owing to have two groups of lead terminals, two groups of loads can be provided.
In order to guarantee good electric property, the distance between the lead end (being lead terminal again) and dull and stereotyped size all can not be too big, otherwise can influence frequency characteristic; Can not be too little, otherwise can produce electromagnetic interference.Preferably, the distance of passing between described two lead terminals of same flat board is 16.0-18.0mm, and dull and stereotyped length is 24.0-26.0mm.
Based on above-mentioned distance, the diameter of described magnetic conductor is not less than the distance between two lead terminals that pass same flat board, is not higher than 45.0mm.
Description of drawings
Fig. 1 is common mode inductance structural representation of the present utility model.
