Unshielded construction means the magnetic field radiates from the core; keep sensitive analog traces or other magnetics at least one part-width away to avoid coupling. The 1206 (3216 metric) footprint and 2.00 mm seated height fit standard pick-and-place and leave clearance under low-profile enclosures. ## Self-resonant frequency and Q factor — the RF boundary With a self-resonant frequency of 270 MHz, this inductor behaves inductively up to that point; above 270 MHz the parasitic capacitance dominates and the impedance drops. The Q factor of 60 at 100 MHz means the inductor stores energy efficiently at that frequency — useful for narrowband matching or filtering in the VHF band. The inductance is tested at 1 MHz, so the nominal 500 nH value holds at low frequencies; derate the inductance near the self-resonant frequency per the impedance curve in the full datasheet. ## Last Buy — source now or qualify a replacement Murata has placed the LQH31HNR50K03L in Last Buy status. This is the final procurement window before the part becomes unavailable through authorized channels. For existing BOM lines, secure the required quantity now; for new designs, evaluate a pin-compatible alternative from the same LQH31 series or a different Murata inductor family with the same 1206 footprint and 500 nH / 260 mA rating.","metaTitle":"Murata LQH31HNR50K03L 500nH Inductor, 260mA, 1206, Last Buy","metaDescription":"Murata LQH31HNR50K03L drum core wirewound inductor, 500 nH ±10%, 260 mA, 1206 SMD.
