Lorandt explains the inrush capability of the chip bead ferrites Würth Elektronik eiSos WE-MPSB series, and how the peak pulse capability can be measured. He also explains the difference from standard chip bead ferrites to the pulse stable WE-MPSB series. He applies several current pulses to the components to demonstrate the pulse capability, and gives finally some tips what to consider when an input capacitor is used.
