The through-hole form factor is common in breadboard prototyping, MRO repair, and low-volume builds where hand-soldering is preferred over SMD rework.","metaTitle":"LM4040C20ILP 2.048V Shunt Voltage Reference, ±0.5%, TO-92","metaDescription":"Texas Instruments LM4040C20ILP precision shunt reference: 2.048V fixed output, ±0.5% tolerance, 100ppm/°C drift, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"35µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"TO-92-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3100","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040C20ILP/alternatives.json"},"ai":{"faq":[{"question":"What is LM4040C20ILP's listed tolerance?","answer":"The initial tolerance is ±0.5%.
