Semitec’s glass encapsulated NT-4 series thermistor features high heat resistance and high sensitivity. Compared with conventional thermistors, the NT-4 thermistors are smaller, faster in response, and more reliable which makes them suitable for various applications. SEMITEC’S NT thermistors are fully compliant with RoHS DIRECTIVE2011/65/EU.

1. Rated zero-power resistance at each temperature.
2. Other resistance tolerance is also available, please ask us.
3. B value: determined by rated zero-power resistance at each temperature.
4. Time when thermistor reached 63.2% of the temperature difference. The value is measured in the air. (silicon oil)
