The ±10 % tolerance and ferrite core are standard for general-purpose power-supply filtering and DC-DC converter output smoothing where the exact inductance value is not critical. ## Unshielded construction and board layout Unshielded construction means the magnetic field extends beyond the component body — adjacent traces carrying sensitive analog signals or high-impedance nodes should maintain a clearance of at least one part width to avoid parasitic coupling. The self-resonant frequency of 60 MHz places the useful inductive impedance range below roughly 20 MHz for most power applications; above SRF the impedance becomes capacitive. With a Q factor of 20 at 1 MHz this is not a high-Q tuned-circuit inductor — it is selected for its DC resistance and current rating, not for narrowband filtering. ## DC bias and thermal budget The 390 mA current rating is the continuous DC current at which the inductance typically drops 10 % from the nominal value (self-heating limits may be reached earlier depending on PCB copper area). 700 mOhm max DCR produces an I²R loss of roughly 106 mW at rated current — this is well within the dissipation capability of a standard 1210 footprint on a two-layer board with 1 oz copper. ## Production status and procurement Listed as Active in production with no NRND or EOL notices — this part is currently available through standard Murata distribution channels.","metaTitle":"Murata LQH32MN1R8K23L 1.8 µH Unshielded Inductor, 390 mA","metaDescription":"Murata LQH32MN1R8K23L drum-core wirewound inductor, 1.8 µH ±10%, 390 mA, 700 mOhm DCR, 1210 SMD.
