The 3.9 Ohm max DCR sets the I²R loss at that current — roughly 32 mW at full rated current, which is manageable in a 1206 footprint but means the inductor runs warm if the DC bias is sustained near the limit. ## Unshielded, 16 MHz SRF — where the inductance collapses Unshielded construction means the magnetic field radiates — keep adjacent traces and components clear, especially if the inductor sits near a sensitive analog or RF node. The self-resonant frequency of 16 MHz is the point where the inductor's parasitic capacitance resonates with the inductance; above that frequency the component behaves capacitively, so the useful bandwidth for filtering or DC-DC smoothing is well below 16 MHz. Q factor of 35 at 5 MHz tells you the energy loss per cycle at that frequency is moderate — fine for a general-purpose filter or decoupling role, but not a high-Q tuned circuit. The inductance is tested at 1 MHz, which is the standard reference for this value range.","metaTitle":"Murata LQH31MN150K03L 15 µH Wirewound Inductor, 90 mA, 1206","metaDescription":"Murata LQH31MN150K03L 15 µH wirewound inductor, 90 mA, 3.9 Ohm DCR, 1206 package.
