It is qualified to AEC-Q100, making it the automotive-grade variant of the standard LM4041 series — the part for under-hood, chassis, and cabin-domain electronics where the BOM must meet the stress profile of automotive environments. ## 1.225 V rail — what the shunt topology means for your design As a shunt reference, this part behaves like a precision Zener: it sinks current from a supply through an external resistor to regulate the output voltage. The cathode current (65 µA typical) is the minimum bias needed to maintain regulation; the 12 mA output capability lets it drive ADC reference inputs or bias low-power analog circuitry without an additional buffer. ## SOT-23-3 package — footprint and sourcing The part is offered in a standard SOT-23-3 package (also listed as TO-236-3 / SC-59).","metaTitle":"LM4041QAIM3-1.2/NO Shunt Voltage Reference, 1.225 V, ±0.1%","metaDescription":"Texas Instruments LM4041QAIM3-1.2/NO precision shunt reference, 1.225 V fixed output, ±0.1% tolerance, 20 µVrms noise, AEC-Q100 qualified, SOT-23-3, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"65 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041QAIM3-1.2%2FNO/alternatives.json"},"ai":{"faq":[{"question":"Can the LM4041QAIM3-1.2/NO replace the standard LM4041AIM3-1.2?","answer":"Yes, in terms of pinout and electrical specs — both are 1.225 V shunt references in SOT-23-3 with the same tolerance, noise, and temperature coefficient. The QAIM3 variant adds AEC-Q100 qualification, so it is the drop-in replacement for any BOM that requires automotive-grade parts.
