4) Heat dissipation constant

The dissipation constant (δ) is the power required to self-heat the temperature of the thermistor by 1˚C when in heat equilibrium.
Applying voltage to a thermistor allows electric current to flow which increases the temperature in the thermistor. T1 is thermistor temperature, T2 is ambient, and P is power consumption.



Measuring conditions for all parts in this catalog are as follows:
1) Ambient temp is 25˚C
2) Axial and radial leaded parts were measured as shipped.
