The self-resonant frequency of 20 MHz means the inductor behaves as an inductor up to roughly 20 MHz; above that the parasitic capacitance dominates and the impedance rolls off — relevant for switching converters running above 2 MHz where the SRF must be at least 5× the switching frequency to keep the impedance inductive. ## 1812 footprint and board integration The ±20% tolerance on the 10 µH nominal is standard for power-grade inductors — the actual value at 1 MHz test frequency can range from 8 µH to 12 µH, which the downstream converter's control loop must accommodate without going unstable.","metaTitle":"Murata LQH43PN100M26L 10 µH Shielded Inductor, 1.17 A","metaDescription":"Murata LQH43PN100M26L 10 µH shielded wirewound inductor, 1.17 A rated, 1.05 A saturation, 176.4 mOhm DCR max.
