[t] is a measuring temperature indicated at °C that is not related to marking + or -.
** T.C.R. measuring temperature: o°C/+100°C.
*** Thermal time constant and thermal dissipation constant are values measured in stationary air and are typical values,
which are values 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 are 1mA for 100Ω and 0.1mA for 500Ωor 1kΩ.

Ambient Temperature
(°C)
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. The value for 500Ω
at 0°C will be the value obtained by multiplying the resistance value in this table by 5. Similarly, the
value for 1KΩ at 0°C will be the value obtained by multiplying the resistance value by 10.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.

protection
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. The value for 500Ω
at 0°C will be the value obtained by multiplying the resistance value in this table by 5. Similarly, the
value for 1KΩ at 0°C will be the value obtained by multiplying the resistance value by 10.
