EMI Shielding Nickel-Zinc Ferrite Magnetic Ring 9.5x5x20mm

This is a dedicated to a variety of audiophile cables, USB cables, data cables, AV cables, audio and video cables and other wires on the magnetic ring, also known as the ferrite core, no magnetism, can be effectively shielded from EMI interference, isolate or filter out the power supply connecting wires into the equipment circuitry of the high-frequency noise impulses interference, such as audio and video electrical appliances can be used to further enhance the quality of audio and video appliances on the power line is undoubtedly the choice of the audio audiophile friends. Used in the audio cable, video cable and other audiophile wire, which increases the purity of the audio system, reduce the signal line by the power line noise interference.

The shape and size of the ferrite core affects the interference suppression effect, usually the larger the volume of the ferrite core, the better the suppression effect. For a given volume, a longer, thinner core will have a higher impedance than a shorter, thicker core, resulting in better suppression. In the case of bias current, to consider the saturation problem, the larger the cross-section of the ferrite core, the less likely to be saturated, and the larger the bias current can withstand. In addition, the smaller the inner diameter of the ferrite core, the better the suppression effect. In short, the principle of selection of ferrite cores is: in the use of space-permitted conditions, choose the longest possible, as thick as possible and as small as possible core bore.
