Self-resonant frequency of 9.3 MHz — above this frequency the impedance becomes capacitive, so the part is useful as an inductor only below roughly 2–3 MHz in practice, depending on the circuit's impedance tolerance. ## AEC-Q200 and the 125°C ceiling AEC-Q200 qualification means the inductor has passed automotive-grade stress tests: thermal shock, moisture resistance, mechanical shock, and vibration per the AEC-Q200 passive-component standard. ## Unshielded drum core — layout awareness Unshielded construction means the magnetic field radiates from the drum core — in a dense PCB layout the stray field can couple into nearby signal traces or other inductors, so spacing and orientation matter more than with a shielded part.","metaTitle":"Murata LQH43NH560J03L 56 µH Inductor, 180 mA, 1812, AEC-Q200","metaDescription":"Murata LQH43NH560J03L drum-core wirewound inductor, 56 µH ±5%, 180 mA, 1.608 Ω DCR, AEC-Q200.
