If the selection of the BS little change with temperature ring, which is not high permeability magnetic ring, you can solve these problems. However, the high and low permeability there is another question to be considered: the problem is its loss, high magnetic permeability generally like 5K, 10K of magnetic ring connector Nan, its loss is very small, made After finished Tangxia pulse transformer magnetic connectors, magnetic circuit impedance because it is relatively small, the delay time is relatively small, its output waveform can be done well, but it's time to adapt to the problem of the temperature becomes powerless; selection of magnetic At low conductivity, though its surface properties and 5K, 10K is good, but it does not start when you start the phenomenon of light. Choose turns the whole bundle cable through a ferrite bead constitutes a common mode choke, if necessary, Jiang magnetic connector can also be in the ring on top of the cable around a few turns. The more turns, the lower frequency interference suppression effect, the better, but at higher frequencies the noise weak inhibition. In practical engineering, according to the frequency characteristics of the interference current ring to adjust the number of turns. Usually when a wide-band interference signals, you can set both on the cable ring, each magnetic surround different turns, which can interfere with high frequency and low frequency while suppressing interference. From the mechanism of action of the common mode choke point of view, the greater the impedance, the more obvious effects of interference suppression. The common mode choke coil impedance from the common mode inductance Lcm = jwLcm, from the formula is not difficult to see that, for a certain frequency noise, magnetic inductance bigger the better. But the reality is not the case, because there is an actual ring parasitic capacitance, and its existence is parallel with the inductor. When faced with the high frequency noise, capacitive reactance is small, the magnetic inductance short circuit, so that the common mode choke useless.
