390 nH wirewound in a 1206 footprint
The Murata LQH31HNR39J03L is a drum core wirewound inductor in the LQH31 series, delivering 390 nH ±5% in a standard 1206 (3216 metric) surface-mount package. Rated for 330 mA continuous current with a DC resistance of 260 mOhm, this part is sized for power rail filtering and RF decoupling where the inductance value and current rating must both hold across the operating band. The self-resonant frequency sits at 300 MHz, with a Q factor of 60 measured at 100 MHz — the inductor behaves as a pure inductance well into the VHF range before parasitic capacitance takes over.
Fit for RF and power decoupling
The 1206 footprint (3.20 x 1.60 mm footprint, 2.00 mm seated height) is a common size for automated pick-and-place; the ferrite core material keeps core losses low at switching frequencies up to a few MHz. Operating temperature spans -40 to 85°C, covering most indoor and telecom equipment environments; the inductance is tested at 1 MHz, which is the standard reference frequency for this value range.
