Thermal and Electrical Properties
•ꢀ Dissipation constant: (still air) 7 to ꢁ5 mW/K
•ꢀ Thermal time constant: (still air) ꢁ± 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 ±.±25 in (±.635
mm) thick using 2ꢀ silver solder.W
•ꢀ Other tolerances
•ꢀ Other reference temperature
•ꢀ Gold electrodes suitable for wire bonding
•ꢀ Other sizes
