Specifications:
Function of the magnetic ring: the magnetic ring can play a good anti- 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- for frequency 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 suppression effect on the lower for frequency, while the noise suppression effect on the higher for frequency is weak. The number of turns of the magnetic ring shall be adjusted according to the for frequency characteristics of the current. Generally, when the for frequency range of signal is wide, two magnetic rings can be added to the cable, and each magnetic ring has different turns, so that high- for frequency and low- for frequency can be suppressed at the same time. Magnetic ring is an indispensable anti- 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.
