Ring: the name suggests is a guide ring magnet. Ring is commonly used in electronic circuits magnetic interference component connector for high-frequency noise has a good inhibition. Jiang million absorption ring ring connector, also known as ferrite bead, referred ring. It is commonly used in electronic circuit element interference, high-frequency noise has a good inhibition, generally used ferrite material (Mn-Zn) is made. Magnetic ring at different frequencies have different impedance characteristics, generally at low frequencies the impedance is small Dasan magnetic connectors, magnetic performance when the signal frequency increases impedance dramatically. As we all know, the higher the frequency, the more easily radiate out (to buy high-quality computer chassis also to reduce electromagnetic leakage), and general signal lines are no shield, then these signal lines became very good antenna receiving ambient various clutter frequency signal, which signal is superimposed on the original transmission signal, and even change the original transmission of the useful signal. So in ring action, so that the normal useful signal good through Fenggang magnetic connector, but also well suppressed by high-frequency interference signals, and low cost. So everyone in the monitor signal cable, USB cable, and even high-end keyboard, mouse-based point of view of a plastic lump-one ring is not surprising. A magnetic ring appearance under normal lighting conditions may be checked by the visual method. External dimensions of the second magnetic ring with an accuracy of 0.02mm vernier caliper under normal lighting conditions tested. Comprehensive factor 3 ring with "CF-3A-type magnetic sorter" measured excitation current is set to 2.5A, the frequency of 40KHz. 4 laps four magnetic inductance is measured at 1 KHz frequency with "YD2810D type LCR digital bridge." 5 magnetic induced electromotive force with "UI100-frequency power source" and "UI9720 magnetic Dynamic Analysis System" under specified conditions, were measured. 6 [1] magnetic Curie point of use "YD2810D type LCR Digital Bridge" and the measurement precision oven.
