Availability is lot-specific — confirmed at RFQ time. No official successor order code is recorded for this part, so a pin-compatible drop-in from Murata may not exist. ## 22 µH, 3.8 A — the power-stage headroom Rated for 3.8 A continuous with a saturation current floor of 5.3 A (Isat). The 1.5 A margin between rated and saturation means the inductor can handle transient current spikes — from a switching regulator load step or inrush — without the inductance collapsing into hard saturation. The 70 mOhm max DCR sets the copper loss. At 3.8 A, I²R loss is roughly 1 W — budget this into the thermal design, especially in a compact, nonstandard 10.90 mm × 10.00 mm package with a 4.00 mm seated height. ## AEC-Q200 and 155°C — the automotive deployment envelope AEC-Q200 qualification certifies this inductor for automotive-grade stress — thermal shock from -40°C to 155°C, board flex, vibration, and humidity bias. The -40°C to 155°C operating range covers under-hood and engine-bay temperatures with margin. Shielded construction with an iron powder core keeps radiated EMI low and handles the saturation current without the abrupt roll-off of a ferrite core — important for a DC-DC converter feeding a noise-sensitive load like a sensor or MCU.","metaTitle":"Murata DFEH10040D-220M=P3 22µH Shielded Power Inductor","metaDescription":"Murata DFEH10040D-220M=P3, 22 µH, 3.8 A, shielded, AEC-Q200, -40°C to 155°C.
