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.","metaTitle":"Murata LQH31CNR47M03L 470nH Wirewound Inductor, Last Buy","metaDescription":"Murata LQH31CNR47M03L 470nH ±20% unshielded wirewound inductor, 700mA, 210mOhm DCR, 1206 SMD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Wirewound","Series":"LQH31","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Q @ Freq":"-","Shielding":"Unshielded","Tolerance":"±20%","Inductance":"470 nH","Mounting Type":"Surface Mount","Package / Case":"1206 (3216 Metric)","Product Status":"Last Time Buy","Material - Core":"-","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.063\\\" W (3.20mm x 1.60mm)","Base Product Number":"LQH31CN","DC Resistance (DCR)":"210mOhm Max","Current Rating (Amps)":"700 mA","Height - Seated (Max)":"0.079\\\" (2.00mm)","Operating Temperature":"-40°C~85°C","Supplier Device Package":"1206","Frequency - Self Resonant":"180MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/464d3ab2ad0094ea68db0784070895fc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the LQH31CNR47M03L or check current availability?","answer":"The LQH31CNR47M03L is a Last-Buy part from Murata.
