4) Heat dissipation constant

The dissipation constant (δ) indicates the power necessary for increasing the temperature of the thermistor element by 1˚C through self-heating in a heat equilibrium.
Applying a voltage to a thermistor will cause an electric current to flow, leading to a temperature rise in the thermistor. This II intrinsic heating II process is subject to the following relationship among the thermistor temperature T1, ambient temperature T2, and consumed power P.

 

 


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