Glass Thermistors

ATC Semitec’s range of glass NTC thermistors includes NT-4 radial glass beads, ATCD series DO-35 diode style NTCs and FT thin film thermistors, suitable for accurate high temperature control up to 350°C.


Why use glass encapsulated NTCs compared to conventional epoxy coated NTCs?

  • High temperature measurement up to 350°C
  • High Accuracy ±1% tolerance
  • Fast thermal response times : Tc <1s
  • Smaller size – ability to fit closer to or on the heat source
  • Tough & robust giving superior long-term stability & reliability
  • Where moisture ingress or high humidity may be a problem.

Their small size and very stable characteristics makes them highly suitable for applications such as 3D printers, automotive sensors,  home appliances and medical devices.

We also supply these glass thermistors in a wide range of metallic and plastic housings for easier mounting and integration into your device.
