1. The noise generated by the chip inductor is physically caused by magnetostriction, which is amplified through the communication medium. We can look at the waveform of the inductor. If the waveform of the inductor is abnormal, the circuit needs to be debugged. If the waveform is normal and noise occurs, it is a quality issue with the inductor. If such a problem is encountered, customers who purchase our inductor can contact us to replace it at any time. However, Dingci Electronics has not yet encountered any customer quality issues such as noise.

2. Check whether the current of the circuit and the wire diameter of the inductor meet the allowable current. If possible, check the winding and process of the inductor to see if the winding is loose or fixed properly.

There is basically no solution to the noise problem, but we can find ways to reduce the noise and avoid audio to solve the customer's problem. Cutting the communication path is generally the simplest and most effective method, such as strengthening the glue to make the line more solid, or replacing the iron core with less magnetic leakage due to magnetic expansion, which are all simple and effective methods.
