1. Principle of Common-mode inductor from China manufacturer
The working principle of Common-mode inductor from China manufacturer is actually very simple, that is, the use of current to generate a changing magnetic field in the inductor, and the use of Common-mode inductor from China manufacturer is generally connected to the signal or the positive and negative poles of the power supply, so the current signal is reversed, so the resulting The magnetic fields are also reversed, so cancel each other out. However, since they are not perfect devices, they cannot be completely canceled, so impedance is used to represent the ability to weaken the magnetic field.

2. Use environment
Common-mode inductor from China manufacturer is mainly used in EMC scenarios, more for conduction experiments on signal lines and power lines, and some radiation experiments.
3. Classification
Commonly used Common-mode inductor from China manufacturer are divided into two categories:
(1) Common mode inductor for power supply
Generally used for power inlet or high power load output.
(2) Common mode inductor for signal
Mainly for the common mode inductors used by the signal, many of which are dedicated common mode inductors.
Note: In many cases, the Common-mode inductor of communication cannot be used universally. If it is mixed, it is likely to cause communication failure.
