‌ The method of selecting and correctly using magnetic ring inductors ‌

• ‌ Selection method ‌ :

• ‌Consider the application scenario ‌ : according to the size of the circuit board, space size and interference frequency, choose the appropriate magnetic ring type and size ‌.

• Check the magnetic permeability ‌ : The magnetic permeability determines the filtering effect of the magnetic ring. The magnetic ring with high or low permeability should be selected according to the actual demand ‌.

• ‌Check the material ‌ : such as ferrosilicon aluminum alloy magnetic ring suitable for high frequency and high temperature environment, with low loss, broadband characteristics ‌.

• ‌ Usage ‌ :

• Correct installation ‌ : Select an appropriate installation method based on the circuit board layout, such as cable ties or screws, to ensure that the magnetic ring is secure ‌1.

• Wiring ‌ : the connecting cable should bypass the central area of the magnetic ring and be connected to the ground or neutral wire to avoid interfering the current ‌.

• ‌Regular maintenance ‌ : check whether the appearance of the magnetic ring is intact, whether the cable is loose, and ensure that the inductance of the magnetic ring works normally ‌.

The correct selection and use of magnetic ring inductor can effectively suppress electromagnetic interference and ensure the stable operation of the circuit ‌.
