The 15 µH value is the inductance at 1 MHz test frequency, with ±20% tolerance — the standard band for power-grade inductors where the DCR and saturation current are the tighter constraints on the design. Rated for 620 mA continuous DC current, the part reaches 660 mA before the inductance drops by 30% (saturation current). The 348 mOhm max DCR means copper losses at full rated current are about 134 mW — a figure that matters for thermal budgeting in a compact 3×3 mm package. ## AEC-Q200 qualification and 105°C operating ceiling The shielded ferrite construction contains the magnetic flux within the core, reducing radiated EMI into adjacent traces and components — a critical property when the inductor sits next to a switching regulator's input capacitor or a sensitive analog front-end. ## 1212 footprint and surface-mount assembly note Self-resonant frequency is 15 MHz — above this the inductor's parasitic capacitance dominates and the impedance becomes capacitive. For a buck converter switching at 2 MHz, the 15 MHz SRF provides adequate margin; for a 10 MHz switching regulator, verify the impedance roll-off at the switching frequency.","metaTitle":"Murata LQH3NPZ150MMEL 15µH Shielded Power Inductor, 620mA","metaDescription":"Murata LQH3NPZ150MMEL 15µH shielded wirewound inductor, 620mA rated, 660mA saturation, 348mOhm DCR, AEC-Q200, 1212 package.
