In a dense PCB layout, keep adjacent traces and sensitive components at least a few millimeters away to avoid coupling noise into the inductor's field. The 31 MHz self-resonant frequency means the part behaves inductively up to roughly 30 MHz — above that, parasitic capacitance dominates and the impedance drops. The ferrite core material gives stable inductance over temperature and DC bias, though the unshielded design means the inductance drops less under bias than a shielded part would.","metaTitle":"Murata LQH43MN6R8K03L Inductor, 6.8 µH, 450 mA, 1812","metaDescription":"Murata LQH43MN6R8K03L drum core wirewound inductor, 6.8 µH ±10%, 450 mA rated current, 500 mOhm DCR max, 1812 package, active production.
