🛒 Sourcing & Supply Considerations
- Authenticity: Verify product origin through XINGLIGHT authorized channels to avoid counterfeit components with uncertain thermal performance.
- Binning Management: Specify bin codes (J6-J8, UW7-13) during procurement to match your color and brightness requirements.
- Sampling: 👇 Always request samples for prototyping to verify the CRI (Color Rendering Index) compatibility with your specific driver design.
- Lead Time: Confirm stock availability for high-volume orders, as 2835 series demand can fluctuate.
❓ FAQ
Q: What is the maximum current I can drive the XL-2835UWC-05 with continuously?A: The absolute maximum continuous forward current is 150mA. While pulses up to 300mA are allowed (≤0.1ms duty), driving it beyond 150mA continuously risks thermal overload and permanent lumen degradation.
Q: Can this LED be used in a high-temperature environment?A: Yes, the operating temperature range is -40°C to +85°C. However, 💡 derating the drive current is recommended as the ambient temperature approaches the upper limit to maintain reliability.
Q: What precautions should I take during SMT assembly?A: Follow the reflow profile strictly: max 255°C for lead-free or 235°C for leaded processes. Do not exceed 260°C. Ensure the moisture sensitivity level (MSL 3) protocols are followed to prevent popcorning.
Q: How do I ensure color consistency across batches?A: Use the specific Color Temperature grading codes (UW7-10 to UW13-10) provided in the datasheet. Ordering by these specific bin codes ensures the 5500K-7500K range remains consistent for your product.
Q: Is this component ROHS compliant?A: Yes, the datasheet explicitly states that the XL-2835UWC-05 is an environmental protection product compliant with ROHS directives.
