215 nH wirewound in 1206 — RF and decoupling fit
The Murata LQH31HNR21J03L is a drum-core, wirewound ferrite inductor in the LQH31 series, offering 215 nH inductance with ±5% tolerance in a 1206 (3216 Metric) SMD package. 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.
