We're a factory specialized in producing all kinds of toroidal inductor, inductor, common mode choke etc.
Changzhou Southern Electronic Element Factory Co.,Ltd is located in the city of Changzhou,which has a long history in Jiangsu Province.It is situated in the most active economic area in Yangtze River Delta Centre.The transport is very convenient. Expressway,Fast railways run though it.And it only takes one and half hours to reach Shanghai or Nanjing city.Airplane from here is through to major cities in China.
Changzhou Southern Electronic Element Factory Co.,Ltd was founded in 1989.After several years' development and effort,it has invested and opened up three subsidiary companies,in Yancheng city, Huai'an city in Jiangsu Province ,and Lang'xi City in Anhui Province respectively.

And a common mode inductor filter / EMI filter inductor with ferrite core, the bifilar winding, noise suppression best countermeasures, high common mode noise suppression and low differential mode noise signal inhibition, low differential mode noise signal suppression of interference sources, in the high speed signal is difficult to be deformed, small volume, with the balance degree good, easy to use, high quality advantages. Widely used in the suppression of electronic equipment EMI noise, personal computer and peripheral devices USB line, STB, IEEE1394 DVC line, LCD panel, low-voltage differential signal.... The core advantages of ring type:
High initial permeability (this is the basic requirement of common mode inductors) and high saturation magnetic induction intensity, temperature than ferrite body stability can understand for temperature rise is small), frequency characteristics of a flexible, because of the high permeability, small can make a lot of sense, adapt to a broad frequency range;
Because of cost factors, magnetic ring are mostly used in high power supply, enthusiasts describe: "small power with the magnetic loop too high", is justified.
Of course, because of the small size, small power requirements for the volume, using magnetic ring is OK selection.
The comprehensive performance is better than that of the UF system.. If the pressure is not the cost of project, you can consider the use of magnetic ring. I used to ring the actual test, to more low margin. And the sense is also less than the UF.
Say UF/UU series common mode
Material: basically, ferrite, the ferrite is also different, generally MXO- and NXO- nickel zinc manganese zinc. The main advantage of the nickel zinc is that the initial magnetic permeability is lower (less than 1000u), but it can work at a higher frequency (greater than 100MHZ), and remain unchanged. Very strong and great.
NXO is higher than MXO resistivity. The effect of the similar damping of ferrite on the high frequency clutter is released from the high frequency clutter in the thermal energy, which explains the problem of the temperature of the common mode inductor..
