39 µH in a 0806 footprint — where it fits
The Murata LQH2MCN390K02L is a drum core, wirewound inductor in the LQH2 series, offering 39 µH inductance with ±10% tolerance.
Unshielded construction and self-resonant frequency
This part is unshielded, so the magnetic field extends beyond the body — keep sensitive traces or other magnetics at least a body-width away to avoid coupling. The self-resonant frequency is 24 MHz, meaning the inductor behaves inductively up to roughly that point; above it, parasitic capacitance dominates and the impedance drops. Tested at 1 MHz, the inductance value is guaranteed at that frequency.
