Murata has flagged the DFEH10040D-1R5M=P3 as Last Buy, meaning the manufacturer has stopped taking new orders or is about to. This is the last window to secure production quantities for ongoing builds or to stock a lifetime buy. No official successor order code is listed on the lifecycle record. If the BOM needs a drop-in replacement, the sourcing path goes through independent distribution or a parametric cross-reference at the same 10.9 mm x 10.0 mm footprint.
14 A continuous, 19 A saturation — the real load limit
Rated for 14 A continuous at 1.5 µH with a 5 mOhm max DCR. The DC resistance is the thermal bottleneck: at 14 A the I²R loss is just under 1 W, which the 10.9 mm x 10.0 mm iron-powder core must sink without saturating. Saturation current is 19 A, about 36 % above the continuous rating. That headroom handles transient load spikes — a buck converter feeding a 12 A processor core can ride through a 30 % step without the inductance collapsing. Shielded construction keeps the flux contained within the iron-powder core, so adjacent low-profile passives on the same 4.0 mm-high board stack see minimal magnetic coupling.
AEC-Q200 and 155°C — automotive and high-temp deployment
Qualified to AEC-Q200, the passive-component stress-test standard for automotive electronics. This means the part passed accelerated life tests (thermal shock, moisture resistance, vibration) that commercial-grade inductors skip. Operating temperature range spans -40°C to 155°C.
Tape-and-reel packaging for pick-and-place
Supplied on tape and reel (embossed carrier) or cut tape for prototype reels. The 10.9 mm x 10.0 mm nonstandard case fits standard 12 mm or 16 mm tape pockets — confirm the feeder width with the assembly house before loading the reel.
