What is the reason for the abnormal noise of the chip inductor during the operation of the equipment? How to solve it?

What is the analysis of the BIG electronic editor below?

During the operation of the chip inductor, due to the magnetostriction, the amplification through the communication medium will produce abnormal noise, resulting in poor product experience. This situation is generally caused by the unqualified production process and product quality of the chip inductor. If there is abnormal noise during the operation of the chip inductor, it is necessary to check the product quality and production process:

1. Product quality inspection:

Look at the current waveform of the inductor. If the waveform is normal, then there is a problem with the quality of the inductor. If the waveform is not normal, it can be a problem with the circuit and needs to be debugged.

2. Production process inspection:

Check whether the current of the circuit and the wire diameter of the inductor are consistent with the requirements, and check the winding process of the inductor, such as whether the winding is loose.

Solution for abnormal sound of chip inductor:

1. It is generally impossible to solve the noise generated. Once there is abnormal noise during the use of the chip inductor, the only solution is to replace it.

2. For the chip inductor products that have not been used, it can simply and effectively reduce the noise caused by the impregnation of varnish water, the strengthening of the glue, the more solid winding, and the replacement of the iron core with better magnetostriction effect. Influence.
