- Wave Soldering Curve: Not specified in detail.
- Soldering Iron Rework Conditions: Iron tip temperature: 400 (max.); Welding time: 3.5 sec (max.); Iron power: 50W (max.).
Storage Environment
- Storage conditions: Temperature: 10~30, Relative humidity: 60% max.
- Use within 6 months after delivery.
- Weld NTC within 168 hours after opening the moisture-proof packaging.
- If the storage period exceeds 6 months or the indicator color of the HIC card changes, bake before welding (60 * 168hr).
- Avoid storing in corrosive substances like sulfur, chlorine gas, or acid.
- Store products on shelves to prevent moisture and dust.
- Avoid thermal shock, vibration, and direct sunlight.
Usage Precautions
- Operating ambient temperature should be within the specified technical range.
- Install away from heat-generating or combustible components, with a minimum gap of 3mm.
- Wear gloves when handling leads.
- Ensure your product has been evaluated and confirmed according to your company's specifications when integrating Songtian's products.
- Songtian is not responsible for failures caused by usage exceeding the defined product functions in trial use.
- In case of NTC damage, failure may lead to short circuits. Implement fail-safe functions using components like fuses to prevent hazards such as ignition or fire.
