And general signal lines are no shield, then these signal lines became very good antenna to receive all kinds of clutter surrounding environment of high frequency signals, and these power inductors, magnetic coils, color ring inductance, stickers chip inductors, bead inductors, transformers, laminated inductance, electronic news signal is superimposed on the original transmission signal, and even change the original transmission of the useful signal, then in ring action, so that the normal useful signal good through magnetic ring connector price, but also well suppressed by high-frequency interference signals. Choose turns the whole bundle cable through a ferrite bead constitutes a common mode choke, if necessary, can also be in the ring on top of the cable around a few turns. The more magnetic ring turns supply connector, for low 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 so magnetic connector how, as well as on the actual ring ring connector parasitic capacitance, the way it exists in 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.
