| Storage Environment | |
| Recommended Storage Conditions | Temperature: 10~30, Relative Humidity: 60% max. Use within 6 months of delivery. |
| Post-Opening Storage | Weld NTC within 168 hours after opening moisture-proof packaging. Store in moisture-proof packaging with desiccant and HIC card. |
| Baking Recommendation | If storage exceeds 6 months or HIC card indicator changes color, bake at 60 for 168 hours before soldering. |
| Prohibited Storage Conditions | Do not store in corrosive substances (sulfur, chlorine gas, acid) to prevent pin oxidation and reduced solderability. Avoid heat shock, vibration, and direct sunlight. Store on shelves to avoid moisture and dust. |
| Usage Precautions | |
| Operating Environment | Work environment temperature must be within specified technical range. |
| Component Proximity | Install with a minimum 3mm spacing from heat-generating or combustible components. |
| Handling | Wear gloves when handling leads. |
| Product Evaluation | Customer must ensure their product is effectively evaluated and confirmed when integrating Songtian's product. Songtian is not responsible for failures arising from use beyond the defined test specifications. |
| Fail-safe Design | In case of NTC damage which may lead to short circuits, implement fail-safe measures like fuses to prevent fire or smoke hazards. |
