The operating temperature range extends from -55°C to 150°C, providing margin beyond the sensing range for thermal runaway or fault conditions. ## Low-power features for periodic measurement One-Shot and Shutdown Mode features allow the sensor to take a single temperature reading on demand and then power down, minimizing average current draw in battery-powered applications. The 8-bit resolution provides 1°C LSB steps — adequate for thermal monitoring, over-temperature protection, and environmental compensation where sub-degree precision is not required. Accuracy is specified under test conditions of -10°C to 100°C, which covers the typical operating band for most consumer and industrial electronics. ## Production status and compliance The part is ROHS3 Compliant, meeting the latest EU hazardous-substance restrictions for electronic components.","metaTitle":"TMP103FYFFR Texas Instruments Digital Temp Sensor, 8-bit","metaDescription":"TMP103FYFFR digital temperature sensor from TI, 8-bit resolution, ±2°C accuracy, I²C/SMBus output, 1.4-3.6V supply, -55°C to 150°C range, 4-DSBGA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"One-Shot, Shutdown Mode","Resolution":"8 b","Output Type":"I²C/SMBus","Sensor Type":"Digital, Local","Mounting Type":"Surface Mount","Package / Case":"4-UFBGA, DSBGA","Test Condition":"-10°C ~ 100°C (-40°C ~ 125°C)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.4V ~ 3.6V","Operating Temperature":"-55°C ~ 150°C","Supplier Device Package":"4-DSBGA (1x1)","Accuracy - Highest (Lowest)":"±2°C (±3°C)","Sensing Temperature - Local":"-40°C ~ 125°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.42000","currency":"USD"},{"qty":3000,"price":"$0.60800","currency":"USD"},{"qty":6000,"price":"$0.57000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f48d75d791cfd52b9d922072cc5acb83.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What supply voltage does TMP103FYFFR require?","answer":"The sensor operates from 1.4V to 3.6V, compatible with single-cell Li-ion batteries or 1.8V/3.3V logic rails."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TMP103FYFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TMP103FYFFR when reusing this data.
