PIN Power Inductor: RPT129

July 26th 2019

RPT129 series is wound by round wire and assembled with Ni-Zn ferrite core. With small size and high L value (L range:220uH~2000uH), it can meet high insulation voltage demand for LED application.

Like RPT109, RPT129 is a power induction that can be used in 600V high voltage applications. we will keep expanding sumida’s product portfolio to meet the high voltage applications.

Key Features:

  • Ferrite core construction
  • Magnetically shielded
  • Operating temperature range: -40℃~+125℃ (including coil’s self temperature rise)

 

Applications:

High voltage for LED lighting application

※1 Measuring condition at 100kHz 1V.
※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℃).
