| 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. | |
