Active production, AEC-Q200 qualified
The Murata LQH32NH180J23L is an active-production drum core wirewound inductor in the LQH32 series, rated at 18 µH with ±5% tolerance and a 235 mA current rating.
DC resistance and self-resonant frequency
The 768 mOhm maximum DCR sets the I²R conduction loss at 235 mA — about 42 mW self-heating at rated current, well within the ferrite core's thermal budget. A self-resonant frequency of 25 MHz means the inductor behaves as an inductor up to that point; above 25 MHz the parasitic capacitance dominates, so this part suits DC-DC converters and filtering below 10 MHz where the Q factor of 35 at 1 MHz gives reasonable selectivity.
1210 footprint for automated assembly
The unshielded drum core construction means magnetic flux radiates outside the body — keep sensitive traces or low-level analog circuits at least a few millimeters away to avoid coupling.
