Many magnetic specifications and models, creating Asahi after years of effort, has its own ring thousands of specifications, we can supply optional, every ring size has its different characteristics, Xu Chong accumulated over the years of production experience, Here I have said, let us get to know more deeply on the ring. 1. The good performance of the magnetic material is very critical, we are using imported materials, including nickel oxide, zinc oxide, copper oxide, iron oxide, etc. These are called iron ferrite material, ferrite magnetic call that comes out. 2. magnetic molding, molding process, there is no error for this ring size is important, more attention during molding die there take place, this will lead to specification when the magnetic bias or magnetic stamping deformation phenomena. Turns select the whole bundle cable through a ferrite bead constitutes a common mode choke line connector needed to be in the ring on top of the cable around a few turns. The more turns, the lower frequency interference suppression, the better, the higher frequency noise while weak inhibition. In the actual project, according to the characteristics of the interference current frequency magnetic ring to adjust the number of turns. Usually when wide-band interference signal, can be set on the two ring conventional connector cable, each magnetic surround different turns, so you can simultaneously suppress high frequency interference and low-frequency interference. Mechanism of action common mode choke point of view from which the larger brands connector impedance, interference suppression effect is more obvious. The common mode choke coil impedance from the common mode inductance Lcm = jwLcm, not difficult to see from the formula, the noise of a certain frequency, magnetic inductance bigger the better. But the reality is not the case, because there is a parasitic capacitance actual ring connector, its existence is parallel with the inductor. When faced with high frequency noise, the capacitor capacitance is small, the magnetic inductance of the short circuit, so that the common mode choke useless. Line connectors, electronic products factory Song Chong-wook, the connector by the Dongguan Shijie Xu Chong-electronic products factory provided.
