Usage Environment Precautions:
- This product is for general electronic use. RALEC is not responsible for any damages, costs, or losses caused by using this product in special environments.
- For applications in special environments (e.g., high temperature/humidity, corrosive atmospheres, contact with unverified liquids, sealing with unverified resins, cleaning with water-soluble detergents), confirmation with RALEC is required.
Transient Overload Precautions:
- This product may lose functionality due to transient overload. Ensure manufacturing processes and storage prevent transient currents exceeding product specifications.
Handling and Operation Precautions:
- Avoid mechanical stress on resistor edges and protective layers during operation.
- Handle PCBs carefully when separating or fixing them to supports to prevent mechanical stress on resistors.
- Operate within the rated power range. Exceeding rated power can cause temperature rise and equipment damage.
- Set up the operating environment before use if the resistor is expected to receive significant pulse load impacts.
- Evaluate and confirm in your actual application, and ensure fail-safe design for system safety.
Storage and Handling Conditions
- Storage environment: 255, 6015% RH. Shelf life: 2 years.
- Avoid harsh environments such as sea breeze, corrosive gases (Cl2, H2S, NH3, SO2, NO2), direct sunlight, and condensation.
- Maintain correct box orientation during handling and storage. Do not drop or squeeze boxes to prevent damage to electrodes or the body.
