Frequently Asked Questions
What is the nominal resistance of the PTMP6431DYAT?
The PTMP6431DYAT has a nominal resistance of 47kΩ with a ±1% tolerance, providing highly accurate resistance values for temperature sensing without requiring individual trimming or calibration during manufacturing.
What package size does the PTMP6431DYAT use?
The PTMP6431DYAT is housed in a 0402 surface-mount package with body dimensions of 1.2 mm x 0.8 mm x 0.62 mm. This compact footprint is well-suited for miniaturized PCB designs in wearables, IoT sensors, and portable medical devices.
What is the maximum operating current for the PTMP6431DYAT?
The PTMP6431DYAT has a maximum operating current of 0.1 mA. Keeping the current at or below this level minimizes self-heating of the thermistor element, ensuring that measured resistance accurately reflects ambient temperature rather than device self-heating.
How does the PTMP6431DYAT differ from standard NTC thermistors?
Unlike traditional NTC thermistors with highly nonlinear resistance-temperature curves, the PTMP6431DYAT uses Texas Instruments' linearization technology to produce a more linear response, simplifying the firmware calculation and reducing processing overhead in microcontroller-based designs.
What are typical applications for the PTMP6431DYAT?
Typical applications include wearable health monitors, smart home sensors, industrial HVAC controllers, battery temperature management, and portable medical diagnostics where precise, low-power temperature sensing in a compact package is required.
