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.
