NT Thermistor (high temperature, high sensitivity, glass encapsulated)

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.
