RPT109 inductor series is wound by round wire and assembled with Ni-Zn ferrite core. With small size and high L value(L range:560uH๏ฝ2000uH), it can meet high insulation voltage demand for LED application. RPT109 is the only one power inductor that can meet 600V high voltage application. we will keep expanding sumidaโs product portfolio and meet the high voltage applications.
