Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.

Note: RT/R25 ratio is the resistance at temperature (T) divided by the nominal resistance at 25°C. The RT/R25 ratio value is multiplied

by the thermistor’s nominal 25°C value to determine the nominal resistance value at a given temperature in the chart above.
