Resistance-Vs.-Temperature Characteristics

The nominal resistance range for the zero-power resistance at 25°C is shown for each available Material

System. Each Material System is denoted by an ordering Code Letter, a referenced curve number and the

nominal 25°C/125°C resistance ratio. The R-vs.-T curves are on the facing page.
