2DE NTC Thermistor
2DE NTC Thermistor
Description:
Epoxy-coated NTC thermistor with twisted pair Kynar-insulated 28 AWG solid silver- plated copper leads, radial configuration, 3 in (76.2 mm) overall length.
Features:
- R25 values from 50 Ω to 100,000 Ω
- Available in point-matched and interchangeable temperature tolerances
- Available in all R/T Curves
With twisted pair Kynar-insulated leads, the 2DE thermistor series reduces labors cost when the sensors are potted in housings and the leads must be electrically insulated. The 2DE series facilitates the process of attaching extension leads. The 2DE series is also appropriate for applications where the thermistor is exposed directly to ambient room air.

Applications:
- Electronic thermometers
- Battery technology
- Industrial controls
- HVAC
- Food processing
- Cold junction compensation
