The 2.35 A saturation current (Isat) sets the hard ceiling where inductance starts to roll off — stay below that in peak-load transients to keep the ripple current within the converter's stability margin. The 25 mOhm DC resistance (DCR) determines the I²R conduction loss at full load: at 3 A, that's 225 mW dissipated inside the 1212 body. For a 12 V-to-3.3 V buck running at 1 MHz, this inductor's 100 MHz self-resonant frequency leaves plenty of headroom above the switching fundamental, so the core loss stays well below the copper loss. ## AEC-Q200 qualification and temperature range Rated AEC-Q200, this inductor passed the automotive-grade stress tests: thermal shock, moisture resistance, mechanical shock, and vibration. The shielded ferrite core (material - Core: Ferrite) contains the magnetic field within the 3.00 mm x 3.00 mm footprint, so adjacent passives on a dense 1212 layout don't couple noise into the inductor's flux path. This matters in multi-phase converters where two inductors sit side by side — the shield keeps the mutual inductance below 1%. ## Package, storage, and board integration Surface-mount in a 1212 (3030 Metric) case, 3.00 mm per side, 1.50 mm seated height. Supplied on tape and reel (cut tape also available). The reel quantity suits medium-volume pick-and-place; for a prototype run, the cut tape option avoids buying a full reel. Store the reels in a dry environment — the ferrite body is not moisture-sensitive per JEDEC, but the terminations can oxidize in high-humidity storage.","metaTitle":"Murata LQH3NPH1R0MMEL Shielded Power Inductor, 1 µH, 3 A","metaDescription":"Murata LQH3NPH1R0MMEL drum core wirewound inductor, 1 µH ±20%, 3 A rated, 2.35 A saturation, 25 mOhm DCR.

Above this current the inductance drops sharply — the ferrite core enters saturation and the inductor behaves like a short circuit. In a buck converter, the peak inductor current during a load transient must stay below Isat to prevent output voltage droop and potential switch overcurrent."},{"question":"What compliance documentation does Murata provide for this inductor?","answer":"The part carries AEC-Q200 qualification, which includes the full automotive stress-test suite.
