Magnetic ring inductors are actually useful for this purpose

Magnetic Ring Inductor actually has such a use mention magnetic ring inductor, many people know that it is a common Electronic Components, the main role is electromagnetic induction conversion, to deal with electronic products appear electromagnetic disturbance and other problems generated.

And partners may not understand is the motor magnetic ring different frequency magnetic ring has different impedance characteristics, generally low frequency is very small impedance, high frequency when the impedance rises sharply, the higher the signal frequency, the easier the magnetic field radiation out, the general signal line is not shielded, assuming that we now use CAN bus, these signal lines become the perfect antenna, this antenna constantly receive the surrounding high-frequency signals, these signals The superposition of these signals changes the signal to be transmitted in practice, the magnetic ring can be very good after the useful signal, together with the high-frequency stirring signal to press down.
