10 µH power inductor with a saturation ceiling above the rated current
The Murata DFEH7030D-100M=P3 is a 10 µH shielded power inductor in the DFEH7030D series, rated for 3 A continuous with a saturation current of 4.2 A — the 1.2 A headroom between Isat and the rated current means the inductance holds flat through the full operating range in a buck converter or EMI filter leg. Maximum DC resistance is 82 mOhm, which at 3 A produces about 0.74 W of I²R loss — the iron powder core and shielded construction keep the flux contained, so the heat stays in the winding rather than coupling into adjacent traces or components.
NRND lifecycle — plan the BOM migration now
This is not an immediate EOL, but the part is no longer the target for new board spins — existing production runs can continue, but the procurement team should identify a form-fit-function replacement before the next BOM revision cycle.
AEC-Q200 qualification and 155 °C ceiling
The -40 °C to +155 °C operating range covers the full automotive temperature grade 0 envelope and extends into the industrial high-temperature band, making it suitable for engine-bay DC-DC converters, LED headlamp drivers, and high-side switch output filters.
Surface-mount footprint and tape-and-reel supply
Available on tape and reel or cut tape, the part is compatible with standard pick-and-place equipment; the shielded construction eliminates the need for keep-out zones around the inductor in the layout.
