Rated at 110 mA with a maximum DC resistance of 3.9 Ω, this part suits low-current rail filtering, LC snubbers, or noise suppression on sensor supply lines where the small current budget is acceptable. Capable is not qualified; this part carries the rating. ## Unshielded construction and self-resonant frequency — what they mean for your filter design Unshielded construction means the magnetic field extends beyond the package — adjacent traces or components in the same 1210 neighbourhood may couple noise if the layout does not provide clearance. A shielded alternative in the same family would be needed if crosstalk is a concern. The self-resonant frequency is 11 MHz; above that the inductor behaves capacitively. For a buck-converter switching at 2 MHz, the impedance is still inductive and useful — but a filter targeting a 20 MHz common-mode spike would operate beyond SRF and lose effectiveness. Q factor is 40 at 1 MHz, which is moderate for a wirewound ferrite-core part — the resistive losses dominate at this frequency. For a tank circuit requiring higher Q, a ceramic-core inductor would be a better fit.","metaTitle":"Murata LQH32NZ390J23L 39µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH32NZ390J23L drum-core wirewound inductor, 39µH ±5%, 110mA, 3.9Ω DCR, 1210 package, AEC-Q200 qualified.
