The magnetic ring and the connecting cable form an inductor, which is a commonly used anti-interference component in electronic circuits. It has a good shielding effect on high frequency noise, so it is called an absorption magnetic ring. Because it is usually made of ferrite material, it is also called a ferrite magnetic ring (magnetic ring for short). The magnetic ring has different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies, and when the signal frequency increases, the impedance of the magnetic ring increases sharply. It can be seen that the role of inductance is so great. As we all know, the higher the signal frequency, the easier it is to radiate. In general, signal lines do not have a shielding layer. These signal lines become good antennas for receiving various messy high-frequency signals in the surrounding environment. These signals are superimposed on the original transmitted signals, and may even change the original useful signals, seriously interfering with the normal operation of electronic equipment. Therefore, reducing electromagnetic interference in electronic equipment has become a problem that must be considered. Under the action of the magnetic ring, normal and useful signals can pass smoothly, and high frequency interference signals can be well suppressed, and the cost is low. The demand for magnetic rings is huge and the quality requirement is high, so it is necessary to carry out appearance inspection during production to ensure the quality is good.
Following is the case study of magnetic rings inspection.
