We all know that inductor is an electromagnetic induction element wound with insulated wires，belongs to common components. What is toroidal coil inductor? What use does it have? Today, Mingda inductor will introduce about this.
The toroidal inductor is assembled with magnetic ring core and inductive wire , which is a commonly used anti-interference element in circuits. It has a good shielding effect on high-frequency noise, so it is called absorption magnetic ring inductor. It is generally made of ferrite materials, so it is also called ferrite magnetic ring inductor. (ferrite inductor for short). The ferrite ring inductor has different impedance characteristics at different frequencies. In general, the impedance is very small at low frequencies. When the signal frequency increases, the impedance increases sharply. For useful signals, the inductor can make them pass smoothly.
For high-frequency interference signals, the inductor can also play a role in restraining. It plays an important role in electronic products.
