It is rated for 370 mA continuous current with a maximum DC resistance of 800 mΩ — the DCR is the thermal limit that governs the actual current you can push before the part self-heats past the ferrite core's saturation point. At 370 mA the copper loss is I² × DCR = 0.37² × 0.8 ≈ 0.11 W, which is manageable in free air on a standard PCB. ## AEC-Q200 and the self-resonant ceiling Qualified to AEC-Q200, this inductor is tested for the thermal shock, vibration, and solder-heat resistance that automotive and industrial environments demand — it is not just a consumer-grade part. The self-resonant frequency is 50 MHz, which means the inductive impedance holds up to about 10-20 MHz; above that the parasitic capacitance between windings starts to dominate, and the part behaves more like a capacitor. The Q factor is 20 at 1 MHz — a moderate Q that keeps the AC loss reasonable in a buck converter switching at a few megahertz. Unshielded construction means the magnetic field radiates outside the core; keep sensitive traces or other inductors at least 3 mm away to avoid coupling.","metaTitle":"Murata LQH32NZ2R2K23L Inductor, 2.2 µH, 370 mA, 1210","metaDescription":"Active Murata LQH32NZ2R2K23L drum-core wirewound inductor, 2.2 µH, 370 mA, 800 mΩ DCR, AEC-Q200, 1210 package.
