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～2000uH), 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 sumida’s product portfolio and meet the high voltage applications.

※1 Measuring frequency Inductance at 100KHz, 1.0V
※2 Saturation current: This indicates the value of D.C. current when the inductance decreases to over 70% of its nominal value.
※3 Temperature rise current: The actual value of DC current when the temperature rise is △T=40℃ (Ta＝20℃).
