What is an anti-interference magnetic ring?

Maybe you are wondering, what is an anti-interference magnetic ring? Where is an immunity ring usually used? Its role in the end is not big? And so on, today xiaofu to introduce with you respectively.

What is an anti-interference magnetic ring?

Anti-jamming magnetic ring usually refers to a kind of magnetic ring used to reduce or prevent electronic equipment from being affected by external electromagnetic interference, which may come from other electronic equipment, electromagnetic radiation or wireless communications and other sources. For example, electronic products are subject to external disturbance signals, invasion of electronic products, so that electronic products receive external disturbance signal interference, did not operate normally, and anti-interference magnetic ring, just can have this function, as long as the product with anti-interference magnetic ring, it can prevent external disturbance signals invasion of electronic products, can make the normal operation of the electronic products, play a anti-jamming effect, so it is known as anti-interference magnetic ring.

Ni-Zn ferrite core ring for anti-interference, non-magnetic.

Where are anti-interference magnetic rings typically used?

Widely used in various audiophile cables, USB cables, data cables, mouse and keyboard cables, AVG, audio-video cables, etc. In addition, it can also be used for signal cables, instrumentation, switching power supply, DC-DC converter, high-frequency transformers and so on.

How useful are anti-interference magnetic rings?

For some electromagnetic sensitive equipment or equipment that needs to work in complex electromagnetic environment, anti-interference magnetic ring is very necessary. For example, in the field of industrial automation, medical equipment, communication equipment, automotive electronics, etc., the use of anti-interference magnetic rings can reduce the electromagnetic radiation of the equipment to the outside world, preventing interference with other electronic equipment. Improve the ability of the equipment to resist external electromagnetic interference and ensure its normal operation. Meet the standards and regulatory requirements of each country on electromagnetic compatibility (EMC), so that the products can legally enter the market.

At present, the main materials of anti-interference magnetic ring are Mn-Zn ferrite and nickel-zinc ferrite, and the shape type has diversity. When selecting, it should be picked according to the specific frequency range, current size, space limitation and other factors in order to achieve the best anti-interference effect.
