The unshielded construction means the external magnetic field is not contained by a magnetic shield; board layout should keep sensitive traces or other magnetics at a distance to avoid coupling, particularly in power supply input or DC-DC converter output stages where the inductor carries ripple current. ## Parametric fit for the BOM line The 3.3 µH inductance value at 1 MHz test frequency with ±5% tolerance is the primary selection parameter — confirm the target inductance at the circuit's operating frequency, as the ferrite core's permeability rolls off above the self-resonant frequency of 65 MHz. The 425 mA current rating is the DC bias current at which the inductance typically drops by 10% (saturation current); the actual ripple current in the application should stay below this to maintain the inductance value and avoid thermal runaway from the 240 mOhm DCR. A Q factor of 20 at 1 MHz indicates moderate AC losses at that frequency; in a resonant tank or filter circuit, the Q sets the bandwidth and insertion loss — a higher Q inductor would be preferred for narrowband RF applications, but this value is typical for a general-purpose power inductor. Tape-and-reel packaging (Cut Tape also available) is standard for automated pick-and-place assembly; the base product number LQH32NH covers the full inductance range in this construction.","metaTitle":"Murata LQH32NH3R3J23L Inductor, 3.3 µH, 425 mA, AEC-Q200","metaDescription":"Murata LQH32NH3R3J23L drum core wirewound inductor, 3.3 µH ±5%, 425 mA, 240 mOhm DCR, AEC-Q200, 1210 package.
