T.C.R. measuring temperature: 0°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.

***

The electricity which it is charged with in the element is moved to the range that rise in temperature due to a self-heat generation can be ignored. Recommended measuring currents

are 1mA for 100Ω and 0.1mA for 500Ω or 1kΩ. SDT310AP can be used as hot-film sensor. Maximum specified current is 100mA when using under self-heating condition.
