Maximum Operating PowerNTC Thermistors

Maximum Power Dissipation Thermal Time Constant

Definition : The power to reach the maximum operating temperature through self heating when using a thermistor for temperature compensation or as a temperature sensor. (No JIS definition exists.) The Maximum Operating Power, when t ̊C is the permissible temperature rise, can be calculated using the following formula.

(formula) Maximum Operating Power= t×heat dissipation constant
