Rated for 330 mA continuous current with a DC resistance of 260 mOhm, this part is sized for power rail filtering and RF decoupling where the inductance value and current rating must both hold across the operating band. The self-resonant frequency sits at 300 MHz, with a Q factor of 60 measured at 100 MHz — the inductor behaves as a pure inductance well into the VHF range before parasitic capacitance takes over. ## Fit for RF and power decoupling The 1206 footprint (3.20 x 1.60 mm footprint, 2.00 mm seated height) is a common size for automated pick-and-place; the ferrite core material keeps core losses low at switching frequencies up to a few MHz. Operating temperature spans -40 to 85°C, covering most indoor and telecom equipment environments; the inductance is tested at 1 MHz, which is the standard reference frequency for this value range.","metaTitle":"Murata LQH31HNR39J03L 390 nH Inductor, 330 mA, 1206","metaDescription":"Murata LQH31HNR39J03L drum core wirewound inductor, 390 nH ±5%, 330 mA, 260 mOhm DCR, 300 MHz SRF, 1206 package, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Drum Core, Wirewound","Series":"LQH31","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Q @ Freq":"60 @ 100MHz","Shielding":"-","Tolerance":"±5%","Inductance":"390 nH","Mounting Type":"Surface Mount","Package / Case":"1206 (3216 Metric)","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.063\\\" W (3.20mm x 1.60mm)","Base Product Number":"LQH31HN","DC Resistance (DCR)":"260mOhm","Current Rating (Amps)":"330 mA","Height - Seated (Max)":"0.079\\\" (2.00mm)","Operating Temperature":"-40°C~85°C","Supplier Device Package":"1206 (3216 Metric)","Frequency - Self Resonant":"300MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e25d4379cfb80e731ed5285aac1d8b5e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the inductance and current rating of LQH31HNR39J03L?","answer":"It is a 390 nH wirewound inductor rated for 330 mA continuous current, with a DC resistance of 260 mOhm and a self-resonant frequency of 300 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH31HNR39J03L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH31HNR39J03L when reusing this data.
