Note
The self-heating of a thermistor during operation depends on the load applied and the
applicable dissipation factor.
When loaded with maximum allowable current/power and the specified dissipation factor is
taken as a basis, the NTC thermistor may reach a mean temperature of up to 250 °C.
The heat developed during operation will also be dissipated through the lead wires. So the
contact areas, too, may become quite hot at maximum load.
When mounting NTC thermistors you have to ensure that there is an adequate distance
between the thermistor and all parts which are sensitive to heat or combustible.
