- Pure Tin Layer (Tin): 3m (Matte tin)
Application Notes
- Recommended Soldering Conditions: Lead Free IR-Reflow Soldering Profile (J-STD-020 compliant), max temperature 260+5/-0 for 10 seconds; Soldering Iron: 35010 within 3 seconds.
- Recommended Land Pattern Design: Varies by type, refer to document for specific dimensions (A, B, P, Q1, Q2).
- 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 cautious of transient overloads that may cause functional loss.
- Handling and Operation: Avoid mechanical stress on resistor edges and protective layers. Handle PCBs carefully to prevent bending-induced stress on resistors. Operate within rated power limits. Consider pulse load impacts and implement fail-safe design.
Storage and Handling Conditions
- Storage: Store in 255, 6015% RH for up to two years. Avoid corrosive environments, direct sunlight, and condensation.
- Handling: Ensure correct box orientation; avoid dropping or crushing to prevent damage to electrodes or body.
Marking
- Outer boxes for export to mainland China will be marked with the Electronic Information Product Pollution Control Mark and Packaging Recycling Mark.
