Sumida developed CDPH79D72 high current and low DC resistance power inductor. It is assembled with Mn-Zn ferrite BAR CORE and Ni-Zn ferrite POT CORE, which ensures high current and reduces magnetic leakage interference.
- Ferrite core construction
- Magnetically shielded
- L×W×H: 8.8×8.2×7.5mm Max.
- Operating temperature range: -40℃～+125℃ (including coils self temperature rise)
- Filter choke for DC/DC converter, single and polyphase buck converter, input filter inductor for DC/DC converter systems

※1 Measuring condition: 100kHz.
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 30% lower than its initial value. (Ta＝20℃).
※3 Temperature rise current: The value of D.C. current when the temperature of coil becomes △T=40℃. (Ta＝20℃).
