Storage Environment
- Store products under the following conditions and use within 6 months of delivery.
- Temperature: 10~30, Relative Humidity: 60% max.
- Solder NTC within 168 hours after opening the moisture-proof packaging. After opening, store NTC in the moisture-proof packaging with desiccant and HIC card, maintaining the above conditions.
- If the storage period exceeds 6 months, or the indicator color of the accompanying HIC card changes after opening the package, baking (60 * 168hr) is required before soldering.
- Reference data for baking when product humidity exceeds requirements before reflow soldering, after exposure time exceeds shelf life, or when ambient temperature/humidity exceed requirements (shelf life restarts after baking).
- Do not store products in corrosive substances such as sulfur, chlorine gas, or acids, as this may cause lead oxidation and reduce solderability.
- To avoid contamination from moisture, dust, etc., products should be stored on shelves.
- Products stored in warehouses should avoid thermal shock, vibration, and direct sunlight.
Usage Precautions
- The operating ambient temperature should be within the specified technical range.
- Do not install near heat-generating or combustible components; maintain a gap of more than 3 mm to prevent damage.
- Wear gloves when handling leads.
- This specification guarantees the quality of our product as a standalone component. When our product is installed in your product, please ensure your product has been effectively evaluated and confirmed according to your specifications.
- If your trial use of our product exceeds the product functions defined in this test specification, we will not be responsible for any resulting failures.
- When an NTC is damaged, the failure may lead to a short circuit. To prevent hazardous situations such as ignition, smoking, or fire during a short circuit, incorporate fail-safe functions using components like fuses in the circuit.
