Reliability
| Item | Requirement | Test Method |
|---|---|---|
| Solder-ability | Even wetting on the tinned part, tinned area 95% | After dipping the lead out end with flux, immerse it in a tin bath at a temperature of 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% (R =RN-RN') | Conduct the test 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 with a temperature of 260 5 and a depth of 15mm. The tin surface is 6mm away from the lower end of the NTC body and maintained for 10 1 second. After recovering for 4-5 hours under the condition of 25 1 , retest the rated zero power resistance RN'. |

Test Ua: tensile force of 10N for 10 seconds; Test Ub: Bend 90, pull 10N, and continue for 10 seconds; Twist 180, pull 5N, and continue for 10 seconds. After recovering for 4-5 hours under the condition of 25 1 , retest the rated zero power resistance RN'. |

Each high and low temperature cycle has a transition time of 5 minutes in an environment of 251. After conducting temperature cycling tests on the sample, take it out and place it at room temperature (25 1) for 4-5 hours before measuring the zero power resistance RN'. |
| Electrical Cycling Testing | No visible damage, R/RN 20% (R =RN-RN') | Environmental temperature: 25 1 . Cycle count: 1000 times, on/off: 5 s/55 s, test current: 5.0A. After placing the sample at room temperature (25 1 ) for 4-5 hours, measure its zero power resistance RN'. |
| Load Life (Endurance) Testing | No visible damage, R/RN 20% (R =RN-RN') | Environmental temperature: 25 1 . The sample passes through a maximum working current of 5.0A. After 1000 24 hours, it is taken out and placed at room temperature (25 1 ) for 4-5 hours. The zero power resistance RN' is measured. |

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 the following conditions: the change in resistance value caused by self heating can be 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 | Use the following formula to represent the material constant of negative temperature coefficient thermistors: B=T1T2/(T2-T1)ln (R1/R2) or B=2.303[T1T2/(T2-T1)]log (R1/R2) 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
- Temperature: -10+40
- Humidity: 70%RH
- Term: 6 months (First-in/ First-out)
- Place: Do not expose the components to corrosive gas, deoxidizing gas, flammable and explosive gases, oil, water, chemical solutions, or direct sunlight, as this may result in deterioration of characteristics or parameter drift.
