Zero Power Resistance		At 25, when the resistance change caused by the internal heating of the resistor body can be ignored relative to the total measurement error.	See Electrical Parameters
B Value		Calculated using the zero Power resistance value at 25 and 50.	See Electrical Parameters
Thermal Dissipation Constant		The ratio of the change of the dissipation power to the corresponding change of the temperature at specified temperature. The unit is: mw/	See Electrical Parameters
Thermal Time Constant		Under zero power condition, Thermal Time constant is the time required by a thermistor that its body temperature reach 63.2% of the difference between its initial and final temperature.	See Electrical Parameters
Leads Terminal Tensile Strength	No break out and damage Resistance change:within 20%	Apply a 1.0kg load to each lead terminal for 10 seconds.
Leads Terminal Bend Strength	No break out and damage Resistance change:within 20%	Fix the body and hang 0.5kg on one terminal, bend 90; then bend back, then bend 90 in the opposite direction.
Vibration	No substantial damage	Frequency: 10~50Hz, Amplitude: 1.55mm, Direction and time: X, Y and Z directions for 2 hours each.
Solderability	Covered termination: 98%	Solder bath Temperature: 2355, Time: 3S
Resistance to Soldering Heat	Resistance change:within 10%	Dip the lead wire into molten solder of 35010 for 3.00.5 seconds up to a depth of 4.00.8mm. After the specimen shall be left at room ambient temperature for 24 hours, the resistance shall be measured.
