Its AEC-Q200 qualification means it passed the automotive-grade stress tests for temperature cycling, moisture resistance, and mechanical shock — suitable for under-hood and powertrain electronic control units that see -40°C to 155°C ambient. ## Current rating and saturation headroom for DC-DC converter sizing The 9.1 A continuous rating and 12 A Isat give roughly 32 % headroom — the inductor will not saturate before the peak current limit of a 9 A-rated buck converter trips, but the margin narrows at elevated temperatures where the core material's saturation flux density drops. Inductance is tested at 100 kHz, which aligns with the typical switching frequency of automotive DC-DC converters in the 200 kHz–2 MHz range; the actual inductance at the operating frequency and DC bias will be lower than the 1 µH open-circuit value due to the core's permeability roll-off. The shielded construction contains the magnetic flux within the core, reducing radiated EMI into nearby sensitive circuits — a requirement for CAN transceivers and sensor front-ends sharing the same PCB. ## NRND — not for new designs, but still sourced for production support For a production line that already qualifies this inductor, the NRND flag means the last-time-buy window is open but finite; securing a forward-positioned lot against the BOM forecast avoids a mid-production EOL scramble. No official successor order code is recorded in the lifecycle data — a direct drop-in replacement from Murata is not yet assigned, so any substitute would require a board-level requalification. ## Package and board-fit constraints for the rework bench Supplied in Tape & Reel (TR) or Cut Tape (CT) — the reel quantity is not listed here, but the carrier tape pitch and pocket depth are specific to the 7.00 mm body width; confirm the feeder compatibility with your pick-and-place head before programming the reel. The iron powder core material has no moisture sensitivity — no bake-out required before reflow, unlike ferrite cores with organic binders that can absorb humidity and pop during soldering.","metaTitle":"Murata DFEH7030D-1R0M=P3 NRND 1µH Shielded Inductor, 9.1A","metaDescription":"Murata DFEH7030D-1R0M=P3, 1µH shielded power inductor, 9.1A rated, 12A Isat, AEC-Q200, NRND.
