That extra resolution on the remote side matters when you're tracking a fast-changing junction temperature — the finer granularity catches thermal transients a coarser sensor would smooth over. ## Supply voltage and bus compatibility The SMBus output means you can hang it on the same two-wire bus as your other SMBus/I²C devices, as long as the bus voltage matches. No level shifting needed if your microcontroller also runs at 3.3V. The Bulk packaging means you get a tube or tray of individual parts — good for prototyping or small production runs where you don't want a whole reel. ## Temperature range and deployment context That covers most indoor electronics, server racks, and industrial control cabinets — but not automotive under-hood or outdoor winter startups. The test condition of 25°C to 125°C confirms the sensor is characterised across its full range.","metaTitle":"TI LM99-1CIMM Digital Temp Sensor, SMBus, ±3°C, 8-VSSOP","metaDescription":"Texas Instruments LM99-1CIMM digital local/remote temperature sensor.
