18 µH wirewound in an 0806 footprint
The Murata LQH2MCN180K02L is a wirewound inductor in the LQH2 series, offering 18 µH inductance with ±10% tolerance in an 0806 (2016 Metric) surface-mount package. Rated at 190 mA with a maximum DC resistance of 2.34 Ohm, this part is suited for DC-DC converter output filtering and signal-line decoupling where the current draw stays below the bias limit.
Self-resonant frequency and usable band
The self-resonant frequency of 35 MHz marks the upper bound where the inductor behaves capacitively — above this frequency the impedance drops and filtering performance degrades. Inductance is tested at 1 MHz, which is within the component's linear operating region and well below the SRF.
Unshielded construction and PCB layout consideration
This is an unshielded inductor — the magnetic field radiates into the surrounding board area, so keep sensitive traces (high-impedance analog, precision references) at least two part-widths away to avoid coupling.
