FUNCTIONAL PERFORMANCE

The temperature resistance relationships of the PTS series

follow different equations:

For the temperature range of -55 °C up to 0 °C:

And for the temperature range of 0 °C up to +175 °C:

T: Temperature in °C

According to IEC 60751 the values of the coefficients are:

The tolerances values of the PTS series are classified by the

following equations as specified by IEC 60751:

Class F0.3:
