For a 1.8 µH part, this SRF is typical and supports filtering up to the low VHF band. Q factor of 35 at 10 MHz indicates moderate selectivity — useful for tuned circuits or impedance matching where some loss is acceptable, but not a high-Q tank for narrowband RF filters. ## Board-fit and sourcing The 1206 SMD package is a rework-friendly footprint — standard tweezers and a soldering iron handle it on site without hot air. No polarity marking needed; orientation is non-polar. Marked with base product number LQH31MN, the part is unshielded — keep it away from sensitive analog traces or place it 2-3 mm from adjacent magnetic components to avoid coupling.","metaTitle":"Murata LQH31MN1R8K03L 1.8µH Inductor, 150mA, 1206","metaDescription":"Murata LQH31MN1R8K03L drum core wirewound inductor, 1.8 µH ±10%, 150 mA, 2.08 Ohm DCR, 60 MHz SRF, 1206 SMD, -40°C to 85°C.","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)","Ratings":"-","Q @ Freq":"35 @ 10MHz","Shielding":"Unshielded","Tolerance":"±10%","Inductance":"1.8 µH","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":"LQH31MN","DC Resistance (DCR)":"2.08Ohm Max","Current Rating (Amps)":"150 mA","Height - Seated (Max)":"0.079\\\" (2.00mm)","Operating Temperature":"-40°C~85°C","Supplier Device Package":"1206","Frequency - Self Resonant":"60MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3036","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/23793266b202ae546e5047be20f0e556.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest alternative to LQH31MN1R8K03L in the same series?","answer":"Within the LQH31 series, other inductance values (e.g., 1.0 µH, 2.2 µH) share the same 1206 footprint and pinout — the choice comes down to the target inductance for your filter or DC-DC compensation network."},{"question":"What compliance documentation does Murata provide for this part?","answer":"The LQH31MN1R8K03L is supplied in Tape & Reel packaging; Murata typically provides RoHS and REACH compliance declarations on request through the distribution channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH31MN1R8K03L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH31MN1R8K03L when reusing this data.
