SP60 Datasheet, PDF (3/4 Pages) Amphenol Corporation – Ultra-stable Probe Thermistors

Stability Classes (By Nominal Resistance at 77°F (25°C)
Ultra-stable probe thermistors availability depends upon nominal resistance at 77°F (25°C). Stability class is
indicated by a code letter for temperature class and a code number for stability group.
Example: “A1” = .02% maximum change per year at 221°F (105°C) maximum temperature.
