Last-Buy lifecycle — 15 µH, 5.2 A shielded power inductor
The Murata DFEH10040D-150M=P3 is a 15 µH shielded power inductor from the DFEH10040D series, rated for 5.2 A continuous current with a saturation current of 5.9 A. The manufacturer has placed this part in Last Buy status, meaning the production window is closing and remaining stock is being consumed. For any BOM line using this inductor, the procurement decision is time-sensitive — the last-time-buy is already in effect, and availability is limited to existing inventory. AEC-Q200 qualification confirms this inductor meets the automotive-grade stress and reliability testing for passive components, including temperature cycling, moisture resistance, and mechanical shock. The iron powder core and shielded construction keep the magnetic field contained, reducing crosstalk to adjacent circuitry in dense power-stage layouts.
Sourcing reality for a Last-Buy part
With the DFEH10040D-150M=P3 officially in Last Buy, new production from Murata has ceased or is about to. The part is still orderable through independent distribution channels while inventory lasts, but there is no guarantee of replenishment. Buyers should confirm availability at quote time and consider locking in quantities for their remaining production runs.
Parametric fit for power-stage designs
The 15 µH inductance with a ±20% tolerance is typical for buck converter output filters or EMI suppression in automotive and industrial power rails. The 5.2 A continuous current rating and 5.9 A saturation current define the usable load range — the inductor will saturate above 5.9 A, causing a sharp drop in inductance and potential current runaway. The 47 mOhm max DCR sets the conduction loss: at 5.2 A, the I²R loss is about 1.27 W, which the 10.9 mm x 10.0 mm x 4.0 mm package dissipates through the board copper. Surface-mount assembly on a nonstandard package means the PCB footprint must match the manufacturer's recommended land pattern — the 10.9 mm x 10.0 mm body is larger than typical 10 mm x 10 mm inductors, so a layout review is advised before committing.
