DC resistance is 78 mOhm max, yielding an I²R loss of roughly 0.34 W at full rated current — the 3.00 mm × 3.00 mm footprint and 1.50 mm seated height rely on the PCB copper pour and via array to pull the heat out; a board with limited copper under the part will run the core hotter than the 125°C ceiling allows. The self-resonant frequency is 60 MHz — well above the 400 kHz to 2.2 MHz switching range of most automotive DC-DC converters, so the impedance stays inductive across the operating band and the effective inductance does not collapse near the switching fundamental. ## Footprint and supply posture The 1212 (3030 Metric) case is a standard footprint shared across multiple Murata and competitor shielded inductor families — the pad layout is the same, so a BOM swap to a different 2.2 µH shielded inductor from the same footprint family does not require a board respin, though the DCR and saturation point will differ.","metaTitle":"Murata LQH3NPH2R2MMEL 2.2 µH Shielded Inductor, AEC-Q200","metaDescription":"Murata LQH3NPH2R2MMEL drum core wirewound inductor, 2.2 µH ±20%, 2.1 A, shielded, AEC-Q200, 1212 footprint.
