Technical Application Notes
- Recommended Soldering Conditions: Lead Free IR-Reflow Soldering (J-STD-020 compliant), Max temperature 260+5/-0 for 10 seconds; Soldering Iron: 35010 within 3 seconds.
- Recommended Land Pattern Design for Reflow Soldering is provided.
- Environmental Considerations: Not recommended for use in high temperature/humidity, corrosive environments (sea breeze, Cl2, H2S, NH3, SO2, NO2), unverified liquids, or with unverified sealing/coating materials. Cleaning after soldering is recommended, even with no-clean flux.
- Transient Overload: Be mindful of transient overloads that can cause functional loss.
- Handling and Operation: Avoid mechanical stress on edges and protective layers. Be cautious of PCB bending. Operate within rated power limits. Consider pulse load impacts. Evaluate and confirm in actual application for fail-safe design.
Storage and Handling Conditions
- Storage: 255, 6015% RH for two years.
- Avoid: Harsh environments such as corrosive gases, direct sunlight, condensation.
- Handling: Ensure correct box orientation. Do not drop or crush boxes to prevent damage to electrodes or the body.
