Active production, tiny footprint — what the BOM sees
The TMP103CYFFR: Housed in a 4-DSBGA package that measures just 1x1 mm (supplier device package 4-DSBGA), this sensor's footprint is about the size of a grain of sand — plan for precision placement and X-ray inspection after reflow, as the solder joints are not visually inspectable.
I²C/SMBus with one-shot — low-power duty cycling
Digital output via I²C/SMBus interface means the sensor connects directly to a microcontroller's two-wire bus without an ADC — the 8-bit resolution gives 0.5°C per LSB steps, adequate for trend monitoring and over-temperature flags. One-shot and shutdown modes let the part sleep between readings, drawing near-zero quiescent current — useful for thermal profiling in battery-operated gear where the bus is idle most of the time.
