Rated for 75 mA continuous current with a maximum DC resistance of 8 Ohm — the DCR sets the I²R heating floor, so the 75 mA rating already accounts for self-heating at the 85 °C upper operating limit. Self-resonant frequency is 7.5 MHz; above that the component behaves capacitively, so this part suits filtering and energy storage in DC-DC converters and bias networks switching below 2-3 MHz. ## Q factor and test conditions Q is 40 minimum at 796 kHz — the quality factor peaks near the test frequency, so the inductor's AC loss is lowest in the hundreds-of-kHz range typical of mid-frequency power converters. Inductance is tested at 1 MHz, 0.25 V, per the LQH32 series standard — the 120 µH value holds within ±10% at that test point; derate for DC bias per the ferrite core's BH curve.","metaTitle":"Murata LQH32MN121K23L 120 µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH32MN121K23L drum core wirewound inductor, 120 µH ±10%, 75 mA, 8 Ohm DCR, 1210 package.
