470 nH, 700 mA — a last-time-buy inductor for existing BOMs
The Murata LQH31CNR47M03L is a 470 nH wirewound inductor in the LQH31 series, rated for 700 mA continuous with a maximum DC resistance of 210 mOhm. The 210 mOhm DCR at 700 mA means roughly 103 mW of self-heating — negligible for a 1206 footprint in still air, but worth checking against your local ambient temperature rise if the inductor sits near a hot regulator. The unshielded construction leaves the field open — adjacent traces carrying fast edges or sensitive analog signals need a keep-out zone roughly one part width (3.2 mm) in each direction to avoid coupling. For a digital supply rail or a low-frequency filter, the unshielded form is fine.
Last Buy — Murata's end-of-life notification
Murata lists the LQH31CNR47M03L as Last Buy. The 1206 (3216 Metric) footprint is a standard size shared by thousands of inductors, so a drop-in replacement from another manufacturer's LQH31-like series is possible — but pin-compatibility depends on the exact inductance, DCR, and current rating matching your BOM line. No second-source is documented here.
