Speaking of the racetrack-shaped magnetic ring , many people may be very strange. Even if some of the products that people usually buy have the existence of a racetrack-shaped magnetic ring , the public may not know that this is a racetrack-shaped magnetic ring even if they see it. Therefore, the understanding of it is even rarer, but in fact the frequency of the racetrack-shaped magnetic ring is still relatively high in life. In the following content, we will introduce the runway-shaped magnetic ring .

In many electronic circuits, the racetrack-shaped magnetic ring cannot be lacking, because the racetrack-shaped magnetic ring is a commonly used anti-interference component, which has a good suppression effect on high-frequency noise, and is generally made of ferrite material. . Generally speaking, the racetrack-shaped magnetic ring has different impedance characteristics at different frequencies. When the low frequency is encountered, the group resistance is relatively small, and when the signal frequency is increased, the impedance of the racetrack-shaped magnetic ring will be Sharply increased. Perhaps we don't know that the higher the signal frequency of many electronic components, the easier it is to be radiated. This is why many people need to reduce the electromagnetic leakage when purchasing a high-quality computer case. The ordinary signal lines have no shielding layer, but If there is a racetrack-shaped magnetic ring , the signal can be smoothly passed and accepted, and even for some interference signals can be shielded. Nowadays, all the high-end keyboards, mice, etc. that are purchased have such a racetrack-shaped magnetic ring. The only difference is that the size of the racetrack-shaped magnetic ring is different. The performance of receiving signals after use is also very good.

After the above introduction, everyone's understanding of the runway-shaped magnetic ring should be relatively deep, and then you can pay attention to when you buy the corresponding electronic products.
