300 degrees celsius glass sealed ntc thermistor, low cost
Glass encapsulated thermistors provide a low cost option for applications that require superior stability and high temperature operation. The thermistors are glass encapsulated to allow for operation in a wide array of environments including high humidity and rapid thermal cycling. The small size allows the sensor to react quickly to small temperature changes. Contact the factory for specific design or application information or the availability of options.
