[ t ] is a measuring temperature indicated at ℃ that is not related to marking ＋・−.
T.C.R. Mesuring Temperature : 0℃/+100℃.
Thermal time constant is value measured in stationary air and is typical value, which is value of element and vary with connecting or fixing methods.
Self-heating coefficient expressed in ℃/mW is values measured at temperature : 0℃ in flowing oil with a velocity >0.2m/s, which is value of elements and vary with connecting or fixing methods.
Specified current is a current value that is used at reliability test under the condition of self heat-generation that can be disregarded. Recommended measuring currents 1mA for 100Ω.

Note: Desired temperature values are obtained by adding temperatures in the vertical and horizontal axes.
When calculating a resistance value of 105°C, read the value in the column where 100°C in the
vertical axis and 5°C in the horizontal axis cross. The value will be 140.40Ω.
