Magnetic Ring Inductor application scenarios, what it does

We all know that an inductor is an electromagnetic induction element made of insulated wire winding. It is a commonly used component. So what is a magnetic ring inductor? What does it do? Today, I will explain to us.

The role of magnetic ring inductor magnetic ring inductor role: magnetic ring and coupling cable constitute an inductor, it is commonly used in electronic circuits, anti-disturbance components, on high-frequency noise has a good shielding effect, so it is called absorbing magnetic ring, due to the general use of ferrite materials made, so also known as ferrite magnetic ring (referred to as magnetic ring). The top is a one-piece magnetic ring, and the bottom is a magnetic ring with equipment 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 sharply larger. The role of inductance is so great, we all know that the higher the signal frequency, the more easily radiated, and the general signal lines are not shielded, these signal lines become a very good antenna, accepting a variety of messy high-frequency signals in the surrounding environment, and these signals superimposed on the original transmission signal, and even change the original transmission of useful signals, and seriously disturb the normal operation of electronic equipment, so drop Electromagnetic disturbance (EM) of electronic equipment is already a necessary consideration. In the role of the magnetic ring, even if the normal useful signal passes smoothly, and can well suppress high-frequency Yu disturbance signal, and the cost is low.
