Please confirm technical specifications before you order and/or use.1/06/09 circuit protection * 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 100Ωand 0.1mA for 500Ωor 1kΩ. SDT310 small type platinum thin film thermal sensors

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 1KΩat 0°C will be the value obtained by multiplying the resistance value by 10.
