The main function of the magnetic beads is to suppress high-frequency interference. In this circuit of the figure below, the resonant frequency of the two magnetic beads is 100 MHz. Then in the USB2.0 480Mbs communication, these two beads are no longer applicable. The magnetic beads are not added well. The magnetic beads should be selected according to the frequency of suppression. The resonant frequency must be higher than at least 5 times the operating frequency. On this basis, look at the impedance and other parameters. we are professional disposable vape manufacturer from shenzhen china and can offer one stop oem& odm vape service.
