Reliability Testing
| Item | Requirement | Test Method |
|---|---|---|
| Solderability | Even tinning on the wetted part, Tinning area 95% | After dipping the lead out end with flux, immerse it in a tin bath at 245 5 and a depth of 15mm, with the tin surface 6mm away from the lower end of the NTC body, for 3 0.5 seconds. (Refer to IEC68-2-20 /GB2423.28 Test Ta) |
| Resistance To Soldering Heat | No visible damage, R/RN 20% | Conduct according to IEC68-2-20 (GB2423.28) Test Tb. Using the welding groove method, the lead out end is dipped in flux and immersed in a tin groove at 260 5 and a depth of 15mm, 6mm away from the lower end of the NTC body, maintained for 10 1 second.

Parameter Definitions
| Item | Units | Definition |
|---|---|---|
| Zero power resistor R25 | The DC resistance value of the thermistor measured at the specified temperature (251); The measurement should be carried out under conditions where the change in resistance value caused by self-heating is negligible relative to the total measurement error. | |
| Resistance tolerance | % | The maximum allowable deviation range of the actual resistance value of the resistor from the nominal value. |
| Thermal dissipation coefficient | mW/C | The power consumed to raise the temperature of the thermistor by 1 . Usually the ratio of power consumption change to temperature change in thermistors at a specified temperature. |
| Thermal time constant | s | The time required for the temperature of a thermistor to drop to 63.2% of its initial and final temperature under zero power conditions. |
| Maximum steady-state current Imax | A | The maximum current that can be continuously applied to a thermistor under ambient temperature conditions of 25 . |
| Maximum impulse capacitance Cmax | F | The maximum allowable capacitance value of a capacitor connected to a thermistor under load conditions. |
| Material Constant B | K | Represents the material constant of negative temperature coefficient thermistors using the formula: B=T1T2/(T2-T1)ln (R1/R2) or B=2.303[T1T2/(T2-T1)]log (R1/R2), where T1=298.15K(25C), T2 = 323.15K(50C). |
| Working temperature range | Thermistor design allows for continuous operating temperature range in zero power state. |
Storage Conditions
| Parameter | Value |
|---|---|
| Temperature | -10+40 |
| Humidity | 70%RH |
| Term | 6 months (First-in/First-out) |
| Place | Avoid exposure to corrosive/oxidizing gases, flammable/explosive gases, oil, water, chemical solutions, and direct sunlight to prevent performance deterioration or parameter drift. |
| Handling after seal open | After unpacking the minimum package, reseal it promptly or store it inside a sealed container with a drying agent. |
