470 nH, 4 A — the DC-DC rail inductor for tight board budgets
The Murata DFE252012PD-R47M=P2 is a shielded wirewound power inductor in the DFE252012PD series, built around a metal-alloy core that handles 4 A continuous with a saturation floor of 5.2 A.
AEC-Q200 qualification — the screening gate for automotive and industrial power stages
AEC-Q200 qualification means this inductor has passed the full stress suite — thermal shock, moisture resistance, mechanical shock, vibration, and solderability — required for automotive-grade passive components. The shielded construction and metal-alloy core suppress radiated noise in the switching loop of a buck converter, which is why this series appears in infotainment head units, ADAS camera modules, and engine-control power supplies. The 125°C upper operating limit covers under-hood ambient plus self-heating margin; a 4 A rail at 85°C ambient still has headroom before the core saturates.
