- Lead-Free: Peak temp 255°C, time above 217°C: 60-120s.
- Leaded: Peak temp 235°C, time above 183°C: 60-150s.
- Packaging: Supplied in EIA standard compliant tape and reel formats, facilitating high-speed SMT pick-and-place automation.
📦 Sourcing & Supply Considerations
When integrating the XL-2835BGWC-05 into production, supply chain consistency is critical.
- Bin Selection: Verify specific Brightness (J4-J6) and Voltage (N13-3 to N13-5) bin codes to ensure uniformity across batches.
- Quality Assurance: 💡 Confirm compliance with ROHS directives and request reliability test data (e.g., 1000h operating life) for high-volume orders.
- Authenticity: Always source through authorized channels to guarantee correct handling of MSL 3 moisture sensitivity standards.
❓ FAQ
Q: What is the maximum current I can drive the XL-2835BGWC-05 with continuously? A: The Absolute Maximum Rating for continuous forward current is 150 mA. While pulse currents can reach 300 mA, you must ensure the average current does not exceed 150 mA to avoid thermal overstress.
Q: What does the Moisture Sensitivity Level (MSL) 3 mean for my assembly process? A: MSL 3 means the components must be mounted within 168 hours (1 week) of opening the vacuum-sealed bag. If floor life exceeds this, you must bake the components according to J-STD-033 standards to prevent popcorning damage during reflow.
Q: Can I use a standard lead-free reflow profile for this LED? A: Yes, the datasheet explicitly supports lead-free processes. The peak temperature should not exceed 255°C, and the time above 217°C should be strictly controlled between 60 to 120 seconds.
Q: What is the typical forward voltage range I should design my driver for? A: At 150 mA, the forward voltage ranges from 2.8V to 3.4V. Design your driver circuit to accommodate this range, typically targeting the median (around 3.1V) for optimal efficiency.
Q: How is the brightness sorted for this model? A: Brightness is sorted into specific codes: J4 (33-39 lm), J5 (39-45 lm), and J6 (45-52 lm). Ensure you specify the required bin code when purchasing to maintain consistent brightness across your lighting product.
