The method of measuring the production of ferrite bead size: When measuring a ferrite ring size, we do some window-dressing, the first appearance of the eyes to detect ferrite bead specifications, nicks or burrs with a ferrite against those surfaces magnetic product specifications, in the measurement, go awry and so on. So how do we avoid these problems in the production, every step of the production process have a good grasp, especially during grinding can lead to ring with notches and burrs and other phenomena occur, so this step should be very aware that when through the grinding machinery . First, the first mechanical fine, the grinding process, we should always optimistic, avoid grinding leads to a gap, as well as to control the grinding time, period of time there will be a ferrite bead with burrs, mill for too long, can lead ferrite bead size, an error occurs smartphones harness Which is good, with mold foot inconsistent phenomena, so whether it is good that checks should step process, so as to produce a perfect ferrite body ring specifications. Turns select the whole bundle cable through a ferrite bead constitutes a common mode choke harness manufacturers selling smartphone, smartphone harness required shelf can also be on top of the cable ring 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. Often when the band interference signal is wide smartphone harnesses, cables can be fitted over the two ring, each magnetic surround different turns, so you can simultaneously suppress high frequency interference and low-frequency interference. Mechanism of action from the point of view of the common mode choke coil, the greater the impedance, the more obvious the effect of interference suppression. 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 the actual ring also parasitic capacitance, and 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.
