SUMIDA: Produkt News
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 coils 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℃).
