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.
Key Features:
- 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)
Applications:
- Filter choke for DC/DC converter, single and polyphase buck converter, input filter inductor for DC/DC converter systems
Parts List:
| wdt_ID | Part Name | Inductance [Within] (μH) ※1 | D.C.R. at 20℃ [Within](mΩ) | Saturation Current (A) Max.(Typ.) ※2 | Temperature Rise Currrent (A) ※3 |
|---|---|---|---|---|---|
| 1 | CDPH79D72NP-2R2MC | 2.20 ± 20% | 4.60 ± 10% | 10.00 (12.50) | (16.50) |
| 4 | CDPH79D72NP-6R8MC | 6.80 ± 20% | 22.50 ± 10% | 6.00 (7.50) | (5.50) |
※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 currently: The value of D.C. current when the temperature of coil becomes △T=40℃. (Ta＝20℃).
