Specifications:
Function of the ring: the 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 ring, normal and useful signals can pass through well, and high-frequency signals can be well suppressed. So it is not surprising that you can see rings on electronic equipment, machinery, even high-end data lines and signal lines.
If you want to play a greater role in the ring, you can wind the cable on the ring several turns. The more turns, the better the suppression effect on the lower frequency, while the noise suppression effect on the higher frequency is weak. The number of turns of the ring shall be adjusted according to the frequency characteristics of the current. Generally, when the frequency range of signal is wide, two rings can be added to the cable, and each ring has different turns, so that high-frequency and low-frequency can be suppressed at the same time. 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.
