17. Inductor Selection

Question.9

Hardware Developer is selecting the output inductor for a buck converter delivering 3.3V at 1.5A continuous (2A peak) with ~1.2A peak-to-peak ripple. Her calculated requirement:

4.7µH ±20%, shielded SMD power inductor, I_sat ≥ 2.5A, I_rms ≥ 2A, DCR ≤ 100mΩ

She chooses the DigiKey part number: 732-1054-1-ND (Würth Elektronik 74405024047)

Is this the correct component for the given requirement?
