Semitec NT-4 Glass NTC Thermistor

Semitec’s NT series glass bead thermistors have a very fast response time and wide operating temperature range from -50°C to 300°C.

The glass coating is extremely robust and ensures the thermistor is moisture-proof.
These high temperature thermistors use lead-alloy technology to ensure long-term stability.

This superior performing Semitec NT-4 NTC thermistor supersedes the Semitec GT-2. Compared with conventional thermistors, the NT-4 thermistors are smaller, faster in response, and more reliable which makes them suitable for various applications.
