What are the main applications of magnetic ring common mode inductors?

December 06, 2022

The higher the magnetic permeability of the Magnetic Ring Inductor, the lower the temperature it can withstand. If the inductance of the magnetic ring inductor is very high, the number of Coils wound in the inductor can be reduced, as well as the use of large wire diameter copper wire winding. Choose the right core according to your needs, but the general principles of core selection for magnetic ring Inductors remain the same, with the following points.

1, the specifications of the magnetic ring should be complete, smooth, no raised areas, and the longer the better.

2, in the low frequency band frequency, it is recommended that the cable winding 2-3 turns can be, high frequency band frequency, the cable is not allowed to wind turns.

3, the aperture of the magnetic core and the tighter the combination of the cable through the better.

What is the relationship between the color of the magnetic ring and the material?

Most magnetic rings need to be painted to facilitate the distinction. Generally, iron powder cores are distinguished by two colors, commonly used are red/transparent, yellow/red, green/red, green/blue and yellow/white, manganese core rings are generally painted green, and iron-silicon aluminum are generally all black, etc. In fact, the color of the ring common mode inductor after firing and with the subsequent spraying of paint coloring is not necessarily related, but only the industry inside the agreement.
