The 65 mA current rating is the DC bias current at which inductance typically drops 10% — stay below this to keep the filter corner where the schematic expects it. DC resistance is 12.5 Ohm max — at 65 mA the I²R loss is about 53 mW, negligible for most signal-filtering roles but a factor if this sits in a bias supply where every milliwatt counts. Self-resonant frequency is 5 MHz; above that the impedance rolls off as the parasitic capacitance dominates. Use this inductor below 2-3 MHz for a clean inductive response. ## Unshielded construction — layout clearance matters This is an unshielded drum-core inductor — the magnetic field extends beyond the body. Keep adjacent traces or copper pours at least 2-3 mm away to avoid coupling noise into nearby signal paths. In a dense 1210 layout, that clearance often means the inductor gets its own exclusion zone on the ground plane. The ferrite core material gives a Q factor of 40 at 796 kHz — moderate selectivity for tank circuits or bandpass filters at that frequency. Below 100 kHz the Q drops; above 1 MHz it rises until the core losses catch up. ## Active lifecycle — no rush, but store the reels dry Status is Active per Murata's product lifecycle — no last-time-buy notice, no successor announced. The LQH32 series is a long-running standard footprint, so second-sourcing from other 1210 ferrite-core wirewound inductors is straightforward if the BOM ever needs it. The reel is Tape & Reel (TR) with Cut Tape (CT) option; store below 30°C and 60% RH to keep the carrier tape from curling.","metaTitle":"Murata LQH32MN271J23L 270 µH Unshielded Inductor, 65 mA","metaDescription":"Murata LQH32MN271J23L drum core wirewound inductor, 270 µH ±5%, 65 mA, 12.5 Ohm DCR, unshielded, 1210 package.","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":"LQH32","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Q @ Freq":"40 @ 796kHz","Shielding":"Unshielded","Tolerance":"±5%","Inductance":"270 µH","Mounting Type":"Surface Mount","Package / Case":"Nonstandard","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Base Product Number":"LQH32MN","DC Resistance (DCR)":"12.5Ohm Max","Current Rating (Amps)":"65 mA","Height - Seated (Max)":"0.087\\\" (2.20mm)","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"1210 (3225 Metric)","Frequency - Self Resonant":"5MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cfd82089124c69e5e21a12ea773111de.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH32MN271J23L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH32MN271J23L when reusing this data.
