Package and board integration for tight layouts
Housed in a 4-DSBGA package measuring 1x1 mm (supplier device package 4-DSBGA), the TMP103FYFFR occupies minimal PCB area — suitable for wearable, IoT, and portable device designs where board real estate is at a premium. 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.
