DG Series Application Benefits

    • Provides faster, more accurate, and less expensive alternatives to thermocouples and RTD probes
    • Free from limitations due to solder temperature, which enables them to offer users a wide operating temperature range of −55 °C to +200 °C.
    • The sensing thermistor’s small size allows for encapsulation in a variety of housings, such as ring lugs and hex nuts



  • Available in four resistance values at 25 °C: 10 kΩ,40 kΩ, 50 kΩ, and 100 kΩ
  • Tolerances down to +- 2 %
  • Dissipation constant of 3.0 mW/°C
  • Thermal time constant of 6 s
  • TCRs of –3.9%/°C, -4.40 %/°C, and -4.75 %/°C
  • Beta values of 3500 °K, 3950 °K, 4036 °K, and 4200 °K
  • 32 AWG dumet wire leads
