- Manual Soldering: Max 260°C for ≤6 seconds. ⚠️
- Moisture Sensitivity: Classified as MSL 3. Ensure proper baking before reflow if floor life is exceeded to prevent "popcorning" damage.
🤝 Sourcing & Supply Considerations
- Binning Verification: Confirm specific Brightness (H8-J2) and Voltage (N13) bin codes with the supplier to ensure batch-to-batch optical consistency.
- Supply Chain Compliance: Verify that stock complies with ROHS directives for environmental safety.
- Sample Evaluation: Request aged samples for life-cycle testing, specifically checking lumen maintenance at 60mA drive currents.
- Authenticity: Cross-reference packaging markings with datasheet revisions to avoid mixed or counterfeit batches in mass production.
❓ FAQ
Q: What is the typical forward voltage range for the XL-5050WWC?
A: The forward voltage (Vf) ranges from a minimum of 2.8V to a maximum of 3.4V when driven at the rated current of 60mA. Designers should select driver circuits that accommodate this voltage spread (N13-3 to N13-5 bins).
Q: Can this LED be used in outdoor applications?
A: The datasheet specifies Indoor Lighting and Advertising Modules as primary applications. While the storage and operating temperatures (-40°C to +85°C) suggest robustness, the package is not specifically rated for high UV exposure or direct water ingress (IP rated) without additional enclosure protection.
Q: What is the moisture sensitivity level (MSL) for this component?
A: The XL-5050WWC has an MSL rating of 3. This means it can be exposed to ambient factory conditions (≤30°C / 60% RH) for 168 hours before requiring baking to prevent moisture-induced damage during reflow soldering.
Q: What is the maximum current I can drive the LED with?
A: The Max Continuous Forward Current is 60mA. While it can handle pulses up to 120mA (provided the pulse width is ≤0.1ms and duty cycle ≤1/10), driving it continuously above 60mA will likely degrade the junction and shorten lifespan.
Q: How should I handle the soldering process for this LED?
A: Use an Infrared Reflow soldering process. For lead-free profiles, the peak temperature should not exceed 255°C, with time above 217°C limited to 60-120 seconds. Manual soldering should not exceed 260°C for more than 6 seconds.
Q: How is the color temperature consistency managed?
A: XINGLIGHT uses Color Temperature Grading codes (e.g., WW2-4 for 2800-3000K and WW4-4 for 3000-3200K). Procurement orders must specify the desired bin code to ensure uniform color appearance across the final product.
