(1) Tolerance given between 15°C and 35°C. Typical value corresponds to a relative resistance change of
–4.68%/°C. Definition of β is ∆lnR/∆(1/T) with T in K. (Naperian logarithm).
Note: when measuring resistances with an ohm meter, please take care that the internal protection diodes,
as indicated in the functional diagram below, are always reverse biased.
