That DCR at this current means about 65 mW of copper loss at full load — negligible for most filtering and decoupling roles, but worth checking if the trace runs near a temperature-sensitive device on the board. The self-resonant frequency of 18 MHz tells you the inductor stops looking inductive above that point — for a 1 MHz switching regulator output filter, it has plenty of headroom, but for RF matching above 10 MHz the parasitic capacitance starts dominating. ## Unshielded construction — placement matters This is an unshielded drum-core design, meaning the magnetic field radiates beyond the component body. In a dense layout, keep sensitive traces or other magnetics at least a few mm away — the field can couple into adjacent signal paths, especially at higher frequencies near the SRF. ## Active production — no last-time-buy pressure The Q factor of 35 at 1 MHz is typical for a ferrite-core wirewound in this size class — adequate for signal filtering where insertion loss matters, but not a high-Q part for narrowband RF tank circuits. ## Sourcing and fit check The ±10% tolerance on 12 µH is standard for power and signal filtering; if your design needs tighter tolerance, the LQH32 series also includes ±5% variants in the same footprint.","metaTitle":"Murata LQH32MN120K23L 12µH Drum Core Inductor, 180mA","metaDescription":"Murata LQH32MN120K23L 12µH unshielded wirewound inductor, 180mA, 2Ω DCR, 18MHz SRF, -40°C~85°C, 1210 SMD.
