Wide range of usesMagnetic rings can play a good anti-interference role. They can prevent display for shielding, snowflakes and surrounding messy signals from invading the device. Under the action of the magnetic ring, normal and useful signals can pass well, and high-frequency interference signals can be well suppressed. Therefore, it is not surprising to see magnetic rings on electronic equipment, machinery, and even high-end data cables and signal cables. The magnetic ring is specially used for EMI interference suppression on multi-strand cables such as power lines and signal lines, including noise and spike interference on power lines. It also has the ability to absorb EMI and electrostatic pulses, so that electronic equipment can meet the corresponding international standards for electromagnetic (EMI/EMC and electrostatic discharge. When in use, a multi-core cable or a bundle of multi-strand cables can be passed through it. Wearing it more than once can enhance its effect. The impedance values at 25MHZ and 100MHZ frequency points are usually used to measure the absorption characteristics of the magnetic ring. Application range of ferrite magnetic ring 1: electronic equipment, instruments and equipment, medical equipment, electrical equipment, audio equipment, machine equipment, home appliances, communication power equipment, etc.!
