  • Linear resistance change across with temperature compared to non-linear thermistors
    • Simplifies resistance-to-temperature conversion methods
    • Reduces look up table memory requirements
    • Eliminates the need for linearization circuitry or multipoint calibration
    • Decreases the accuracy spread across a wide temperature range
  • 10-kΩ nominal resistance at 25°C (R25)
    • ±1% maximum (0°C to 70°C)
  • Consistent sensitivity across temperature
    • 6400 ppm/°C TCR (25°C)
    • 0.2% typical TCR tolerance across temperature (–40°C to 125°C)
  • Fast thermal response time:
    • 0.6 second for DEC package
  • Long lifetime and robust performance
    • Ultra low power consumption compared to traditional NTCs that lower errors due to self heating
