Thermometrics Thermistors Visit ThermometricOs Website at www.thermometrics.com Precision Thermistors 0.2C from 0C to 75C ThermometricOs precision units are the designersO choice for low cost, close-tolerance temperature measurement. These ultrastable thermistors are accurate to 0.2C from 0C to 75C. They are widely used in OEM applications because they offer close-tolerance temperature measurement without requiring individual calibration. A protective coating is standard for all precision thermistors listed in the table below.

Glass Encapsulated Thermistors Well suited for temperature measurement, control and compensation applications, low cost makes them ideal for high volume applications such as energy management systems, small appliance controls, automotive and industrial equipment controls. These units exhibit faster still air response times than comparable glass probe devices while maintaining a relatively high dissipation constant and are manufactured to closer resistance tolerances. Maximum Power Level: 0.075 watt at 25C (derating to zero watt at 100C). Dissipation Constant In Still Air: 1 mW/C. Thermal Time Constant In Still Air: 10 sec. Although suitable for applications in the temperature range of 80C to +150C, best stability is achieved at temperatures not exceeding 105C. Quantity price breaks are available.
