Rated for 520 mA continuous current with a DC resistance of 110 mOhm, this part suits power-supply decoupling and RF bias-tee applications where the current draw stays under half an amp. ## RF performance: Q factor and self-resonance A minimum Q of 60 at 100 MHz and a self-resonant frequency of 430 MHz mean the inductor maintains its inductive impedance well into the VHF band — useful for filtering in wireless front-ends up to the 400 MHz ISM range. ## Last-buy status and procurement path Murata has placed the LQH31HNR21J03L in last-buy status — this is the final production run, and remaining stock is finite.","metaTitle":"Murata LQH31HNR21J03L Drum Core Inductor, 215 nH, 520 mA","metaDescription":"Murata LQH31HNR21J03L wirewound ferrite-core inductor, 215 nH ±5%, 520 mA, 110 mOhm DCR, 1206 SMD.
