Usage Environment Precautions: This product is for general electronic use. RALEC is not responsible for any damage, cost, or loss caused by using this product in special environments. For other applications, please confirm suitability with RALEC. Special environments include, but are not limited to, high temperature/humidity, corrosive atmospheres (sea breeze, Cl2, H2S, NH3, SO2, NO2), unverified liquids, sealing with unverified resins, and cleaning with water-soluble detergents.
Transient Overload Precautions: This product may lose functionality due to transient overload. Ensure manufacturing processes and storage prevent transient currents exceeding product specifications.
Handling Precautions: Avoid mechanical stress on resistor edges and protective layers. Handle PCBs carefully to prevent bending-induced stress on resistors. Operate within rated power limits to prevent damage from overheating. Assess and confirm product performance in your specific application and implement fail-safe design for system safety.
Storage and Handling Conditions
- Storage: 255, 6015% RH for two years.
- Avoid harsh environments: sea breeze, corrosive gases (Cl2, H2S, NH3, SO2, NO2), direct sunlight, condensation.
- Handle with care: maintain correct box orientation, avoid dropping or crushing to prevent damage to electrodes or body.
