Ni Zn Ferrite Magnetic Rod (Size 12 * 100mm) Designed to Improve Signal Integrity by Reducing High Frequency Noise Specifications: Function of the magnetic ring: the magnetic ring can play a good anti-interference role, and it can prevent display shielding, snowflakes and surrounding miscellaneous signals from invading the equipment. Under the of magnetic ring, normal and useful signals can pass through well, and high-frequency interference signals can be well suppressed. So it is not surprising that you can see magnetic rings on electronic equipment, machinery, even high-end data lines and signal lines. If you want to play a greater role in the magnetic ring, you can wind the cable on the magnetic ring several turns. The more turns, the better the interference suppression effect on the lower frequency, while the noise suppression effect on the higher frequency is weak. The number of turns of the magnetic ring shall be adjusted according to the frequency characteristics of the interference current. Generally, when the frequency range of interference signal is wide, two magnetic rings can be added to the cable, and each magnetic ring has different turns, so that high-frequency interference and low-frequency interference can be suppressed at the same time. Magnetic ring is an indispensable anti-interference component in electronic circuit. It is generally made of zinc oxide, nickel oxide, iron oxide and other ferrite materials through molding, sintering, grinding and other processes. features: Size: 12* 100mm12* 200mm Material: nickel zinc Rectangle ratio 20 Coercivity 35(A/m) Residual magnetism 1200(mT) The package includes: 1* High frequency magnetic rod _x000D_ _x000D_
