It carries a 250 mA current rating with a maximum DC resistance of 624 mOhm, and a self-resonant frequency of 240 MHz — the SRF tells you where the inductive impedance peaks before capacitance dominates, so keep the operating frequency well below this for a clean inductor response. The 1206 (3216 metric) footprint and 2.00 mm seated height fit standard pick-and-place assembly; the unshielded construction means the magnetic field couples into adjacent traces, so maintain clearance from sensitive routing in the layout. ## Last-buy lifecycle — sourcing window is closing Murata has placed the LQH31HNR61K03L in last-buy status — the official production end is announced, and the remaining inventory window is the final opportunity to secure stock through authorized and independent distribution channels. ## Q factor, temperature range, and material The Q factor is specified at 60 minimum when measured at 100 MHz — this is the ratio of reactance to resistance at that frequency, so a Q of 60 means the inductor stores 60 times more energy than it dissipates per cycle at 100 MHz, which matters for tank circuits and impedance-matching networks.","metaTitle":"Murata LQH31HNR61K03L Drum Core Inductor, 610 nH, 250 mA","metaDescription":"Murata LQH31HNR61K03L wirewound ferrite-core inductor, 610 nH ±10%, 250 mA, 624 mOhm DCR.
