In a typical 3.3 V to 1.8 V buck converter running at 600 mA, the conduction loss drops to roughly 28 mW — well within the thermal budget of the 1212 package without forced airflow. The self-resonant frequency of 60 MHz means this inductor stays inductive well above the switching frequency of most intermediate-bus converters (typically 300 kHz to 2 MHz). Above SRF the impedance becomes capacitive, so keep the switching edge rate below 10 MHz to avoid parasitic coupling. ## Shielded construction and temperature range Shielded ferrite core reduces magnetic flux leakage to adjacent traces — important when the inductor sits near a sensitive analog front-end or RF section on the same PCB. Tape-and-reel or cut-tape options available for prototype or production quantities.","metaTitle":"Murata LQH3NPN2R2MMEL 2.2 µH Shielded Inductor, 1.22 A","metaDescription":"Murata LQH3NPN2R2MMEL shielded wirewound inductor, 2.2 µH ±20%, 1.22 A, 78 mOhm DCR, 1212 package, -40 to 105 °C.

The ferrite core saturates softly, so the inductance gradually decreases above 1.8 A rather than collapsing abruptly. For a 1 A rail with 20% ripple, the peak current stays around 1.1 A — well below Isat, so the inductance remains within ±10% of the nominal 2.2 µH."},{"question":"What compliance documentation does Murata provide for this inductor?","answer":"Murata provides RoHS and REACH compliance declarations for the LQH3NPN series.
