  • Publication number: 20210103310
    Abstract: A mobile terminal, including a clock generator, a first frequency conversion circuit, a first module, a second frequency conversion circuit, and a second module. The first frequency conversion circuit performs frequency conversion on a clock signal generated by the clock generator, to obtain a first clock signal, and outputs the first clock signal to the first module. The second frequency conversion circuit performs frequency conversion on the clock signal generated by the clock generator, to obtain a second clock signal, and outputs the second clock signal to the second module. The mobile terminal has an improved anti-electromagnetic interference capability.

  • Publication number: 20180366266
    Abstract: A magnetically shielded power inductor and a method for producing a magnetically shielded power inductor are described. The magnetically shielded power inductor includes a power inductor component and a wave-absorbing material layer. The wave-absorbing material layer is laminated on a surface of the power inductor component. The wave-absorbing material layer is configured to mitigate magnetic field interference to the power inductor component from a surrounding magnet of the wave-absorbing material layer.
