Operation Notice
1.Application:Temperature measure and control；
2.The current flowing through the NTC is controlled within the Pmax range to avoid the measurement error caused by the self-heating of the component.
3.Avoid excessive heat shock,The hot air blow should beat least 30mm to the probe in case heat shrink protection tube need to be attached.
4.Storage Temperature -10℃～40℃,≤75%RH；Avoid in a corrosive gas and sunlit environment; After opening the package, it needs to be sealed again.
