Technical Application Notes
- Recommended Soldering Conditions: Lead Free IR-Reflow Soldering Profile (J-STD-020 compliant), Max temperature 260+5/-0 for 10 sec. Soldering Iron: 35010 within 3 seconds.
- Recommended Land Pattern Design for Reflow Soldering is provided for various types.
- Environmental Considerations: Product is for general electronic use. RALEC is not responsible for damages in special environments. Confirmation required for high temperature/humidity, corrosive gas environments (Cl2, H2S, NH3, SO2, NO2), non-verified liquids, or non-verified sealing/coating materials. Cleaning after soldering is recommended, even with no-clean flux.
- Transient Overload: Be aware of potential functional loss due to transient overloads.
- Handling and Operation: Avoid mechanical stress on resistor edges and protective layers. Be cautious of PCB bending during assembly. Operate within rated power limits. Consider pulsed load impacts. Evaluate and confirm in actual application for fail-safe design.
Storage and Handling Conditions
- Storage: 255, 6015% RH for two years. Avoid corrosive environments (sea breeze, Cl2, H2S, NH3, SO2, NO2), direct sunlight, and condensation.
- Handling: Ensure correct box orientation. Avoid dropping or crushing boxes to prevent damage to electrodes or the body.
Marking
Outer boxes are marked with Electronic Information Product Pollution Control Mark and Packaging Recycling Mark (for export to mainland China).
