Thermal and Electrical Properties
•
•
•
Dissipation constant: (still air) 7 to 15 mW/K
Thermal time constant: (still air) 10 to 45 seconds
The thermal time constant and dissipation
constant values are dependent upon the method
of mounting. The above values represent the range
of smallest to largest HM thermistor chips when
soldering to an aluminum substrate 0.025 in (0.635
mm) thick using 2% silver solder.W
