or glass bead configurations
Description:
SS&C radial leaded 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.

This R/T Conversion Table is provided for reference only. SS&C
uses the Steinhart-Hart equation to calculate the nominal Rt/
R25 value. 1°C tables are available upon request.
• α25 - Negative Temperature Coefficient of Resistance at 25˚C
expressed in %/˚C. This is the percentage change in thermistor
resistance for a 1°C change in its' body temperature at 25˚C. α is
particularly useful in calculating the required resistance tolerance
necessary to guarantee sensor accuracy. α at temperatures other
than 25˚C is available upon request as tables in 1˚C increments.
