Wide range of uses Magnetic rings provide effective anti-interference performance. They help prevent display shielding, snowflakes, and unwanted signal interference from affecting the device. With the action of the magnetic ring, normal and useful signals can pass through smoothly while high-frequency interference signals are suppressed. It is common to find magnetic rings on electronic equipment, machinery, data cables, and signal cables. These rings are specifically designed for EMI interference suppression on multi-strand cables such as power and signal lines, including noise and spike interference on power lines. They can absorb EMI and electrostatic pulses, helping electronic devices meet international standards for electromagnetic compatibility (EMI/EMC) and electrostatic discharge. During use, a multi-core cable or bundle of wires can be threaded through the ring. Passing the cable through multiple times enhances the effect. 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, industrial 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, and more. Installation: Place the magnetic ring over USB cables, data cables, AV cables, video cables, or audio cables to improve signal quality and shield against radiation. Especially effective when installed near the computer end of mouse and keyboard cables, helping to suppress electromagnetic radiation.
