** Thermal time constant and thermal dissipation constant are reference values, which are values of elements and vary with connecting
or fixing methods. Thermal dissipation constant is approx. 4mW/°C under the surface mounting condition.
*** When always using a SDT73S, 200°C or less is recommended.

Note: Desired temperature values are obtained by adding temperatures in the vertical
and horizontal axes. When calculating a resistance value of 105℃, read the
value in the column where 100℃ in the vertical axis and 5℃ in the horizontal
axis cross. The value will be 140.40Ω. The value for 500Ωat 0℃ will be the
value obtained by multiplying the resistance value in this table by 5.
