1.5 µH shielded wirewound for DC-DC rail filtering
The Murata LQH3NPN1R5MJRL is a 1.5 µH ±20% shielded wirewound inductor from the LQH3 series, built on a ferrite drum core. The 58.8 mOhm max DCR keeps I²R losses manageable at 1.1 A — about 71 mW dissipation — so the part stays cool in a dense layout without forced airflow. The self-resonant frequency of 60 MHz sits well above the 1–4 MHz switching range of most buck converters, meaning the inductive impedance dominates at the switching frequency and the SRF won't cause a parallel-resonance dip in the filter response.
1212 footprint and rework reality
The shielded construction means it won't couple switching noise into nearby traces — a real help when the inductor sits next to a sensitive feedback node on a tight PCB.
Sourcing and compliance posture
The base product number LQH3NPN covers the family; the suffix JRL indicates the ±20% tolerance and tape-and-reel packaging. No official cross-reference or second-source is recorded for this exact inductance/tolerance/package combination. If a BOM calls for 1.5 µH ±20% in a 1212 shielded footprint, this is the Murata direct fit.
