10A Magnetic Ring Inductor

Role of magnetic ring inductor: The magnetic ring and the connecting cable form an inductor, which is a common anti-interference component in electronic circuits and has a good shielding effect for high frequency noise, so it is called an absorbing magnetic ring, which is also called a ferrite magnetic ring (referred to as magnetic ring) because it is usually made of ferrite material. In the figure, the top is a one-piece magnetic ring and the bottom is a magnetic ring with a mounting clip. The magnetic ring has different impedance characteristics at different frequencies.
Generally at low frequencies the impedance is very small, and when the signal frequency increases the impedance of the ring becomes dramatically larger. 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 out, and the general signal lines are not shielded, these signal lines become a very good antenna to receive a variety of clutter in the surrounding environment, high-frequency signals, and these signals superimposed on the original transmission of signals, and even change the original transmission of useful signals, serious interference with the normal work of electronic equipment, so reduce Electromagnetic interference (EM) of electronic equipment is already a problem that must be considered. In the role of the magnetic ring, even if the normal useful signals pass smoothly, and can be well suppressed high-frequency Yu disturbance signal, and low cost.
