🚀 Sourcing & Supply Considerations
When integrating the XL-2835YWC-02 into mass production, consider the following supply chain factors to ensure continuity and quality:
- Bin Selection: Verify specific Brightness (H8-J2), Voltage (N13), and Color Temperature (YW) codes with your supplier to match your driver design.
- Authenticity: Source exclusively through authorized XINGLIGHT channels to avoid counterfeit components that may fail reliability tests.
- Sample Support: 👇 Request pre-production samples to validate thermal performance in your specific housing design before full-scale rollout.
- Packaging: Ensure the EIA standard tape packaging matches your feeder setup for SMT lines.
❓ FAQ
Q: What is the maximum forward current for continuous operation? A: The XL-2835YWC-02 supports a maximum continuous forward current of 60 mA. While it can handle peaks up to 150 mA, the pulse width must not exceed 0.1ms with a duty cycle of 1/10.
Q: What does the MSL 3 rating mean for my assembly process? A: An MSL (Moisture Sensitivity Level) of 3 means the components must be mounted within 168 hours (1 week) of opening the dry vacuum seal. If exposed longer, you must bake the components at specified temperatures to prevent "popcorning" or delamination during soldering.
Q: Can this LED be used in high-temperature environments? A: The operating temperature range is -40°C to +85°C. However, to maintain lifespan, the junction temperature must be managed via PCB heat dissipation, especially when driving at the maximum 60mA current.
Q: What is the typical forward voltage range I should design for? A: The forward voltage ($V_F$) ranges from 2.8V to 3.4V at 60mA. Your LED driver should accommodate this variance, or you should select specific voltage bins (N13-3 to N13-5) to ensure uniformity in your light engine.
Q: Is this LED suitable for outdoor lighting applications? A: While the LED itself is robust (IP68 not applicable to component), it is primarily categorized for Indoor and Commercial lighting. For outdoor use, the final luminaire must provide adequate water ingress protection (IP rating) and environmental sealing for the PCB.
