- Recommended Land Pattern Design is provided for Reflow Soldering.
- Users should adjust based on actual application.
- RALEC is not responsible for damages or losses incurred when using this product in special environments not confirmed by RALEC.
- Special environments include, but are not limited to: high temperature/humidity, corrosive atmospheres (Cl2, H2S, NH3, SO2, NO2), non-verified liquids, non-verified sealing/coating materials, and cleaning with water-soluble detergents after soldering.
- Transient overload may cause loss of function. Avoid transient currents exceeding product specifications.
- Handle with care to avoid mechanical stress on the resistor edges and protective layer.
- Ensure resistors are used within their rated power range.
- Evaluate and confirm in the actual mounting state, and ensure system safety with fail-safe design.
Storage and Handling Conditions
- Storage environment: 25±5, 60±15% RH for two years.
