- Refer to baking data for products exposed beyond shelf life or exceeding temperature/humidity requirements before reflow soldering.
- Do not store in corrosive substances (sulfur, chlorine gas, acid) to prevent lead oxidation and reduced solderability.
- Store on shelves to avoid moisture and dust.
- Avoid thermal shock, vibration, and direct sunlight in storage.
Usage Precautions
- Ensure operating ambient temperature is within technical specifications.
- Install away from heat-generating or flammable components (minimum 3mm spacing recommended).
- Wear gloves when handling leads.
- This specification guarantees the quality of the product as a single unit. Ensure your product is effectively evaluated and confirmed according to your company's specifications when integrating our product.
- Songtian is not responsible for failures arising from the use of our products beyond the scope of this test specification.
- In case of NTC damage, failure may result in a short circuit. Implement fail-safe functions using components like fuses to prevent fire hazards.
