What is the reason that the inductor makes a loud noise in the circuit?
1. inductor is transformer, which can change voltage, current and impedance through the number of turns of the primary and secondary side coil. Of course, inductors can also produce magnetic fields. The noise should be caused by electromagnetic waves, especially in parts with loose or gaps.
The frequency of .
2. people's ears can be heard at about 20HZ-20KHZ. If the voice can be heard by the human ear, the excitation frequency can basically be locked. The essence of sound is a kind of noise caused by vibration. The noise is also divided into structural and cavity noise, and the final transmission to the ear is the formation of the compressed air vibrating eardrum in the compressed air or in the cavity noise.
3. the high frequency vibration of the switch mode, try to fix the glue to see that the possibility of elimination is not large, but it can be improved.
Features high power, high saturation current, low impedance and miniaturization
