Wide range of uses: Magnetic rings provide effective anti-interference performance. They help prevent display shielding, snowflakes, and surrounding signal noise from affecting the device. Under the action of the magnetic ring, normal and useful signals can pass through efficiently, while high-frequency interference signals are suppressed. It is common to find magnetic rings on electronic equipment, machinery, data cables, and signal cables. The magnetic ring is designed for EMI interference suppression on multi-strand cables such as power lines and signal lines, including noise and spike interference on power lines. It can absorb EMI and electrostatic pulses, helping electronic equipment meet relevant international standards for electromagnetic compatibility (EMI/EMC) and electrostatic discharge. During use, a multi-core cable or a bundle of multi-strand cables can be passed through the ring. Looping the cable through multiple times enhances the effect. The impedance values at 25MHz and 100MHz are typically used to evaluate the magnetic ring's absorption characteristics. Application range of ferrite magnetic rings: Electronic equipment, instruments, medical devices, electrical appliances, audio systems, machinery, home appliances, communication power equipment, etc. Suitable for power cords, flat cables, data cables, signal cables, USB cables, AC cables, DC cables, audio cables, connecting cables, digital camera cables, computer peripheral cables, etc. Installation: Place the magnetic ring over USB cables, data cables, AV cables, video cables, or audio cables to improve signal quality and shield radiation. Especially effective when placed near the computer end of mouse and keyboard cables to suppress electromagnetic radiation.
