📌 Product Overview
The XL-3020UWC is a 3020 package (3.0x2.0mm) Surface Mount Device (SMD) LED designed by XINGLIGHT. 💡 It features a white light source with a color temperature range of 6000K to 7000K (Cool White), encapsulated in a yellow colloid for optimal light extraction. This component is specifically engineered for high-density automated assembly processes.
The design focus for this model balances luminous intensity (4-8 lm) with a wide 120-degree viewing angle, making it ideal for uniform illumination strips. 👇 Its compact footprint and low thermal mass require strict adherence to moisture sensitivity levels (MSL 3) to prevent pop-corning during infrared reflow soldering.
🚀 Typical Applications
Based on the 120-degree beam angle and compact 3020 form factor, the XL-3020UWC is best suited for applications requiring efficient space utilization and diffuse lighting:
- Indoor General Lighting: ✨ Utilized in fluorescent tube replacements, rigid light bars, and residential downlights where consistent color temperature is critical.
- Commercial & Signage: High suitability for advertising light boxes and illuminated channel letters (advertising words) due to the 120° dispersion.
- LCD Backlighting: Provides uniform edge lighting for liquid crystal displays.
- Decorative Flex Strips: 📈 Designed for flexible circuit boards where low profile (1.3mm height) is a mechanical necessity.

- Soldering Process: Suitable for Infrared Reflow Soldering.
- Lead-Free Process: Peak temp 255°C (+0/-5°C), time above 217°C: 60-120s.
- Lead Process: Peak temp 235°C (+5/-0°C), time above 183°C: 60-150s.
- Packaging: EIA standard compliant tape and reel for automated SMT pick-and-place machines.
🛒 Sourcing & Supply Considerations
- Bin Selection: Verify specific grading codes for Brightness (H3-H5) and Voltage (N13) to ensure uniformity in your final product.
- Authenticity: Source through XINGLIGHT authorized channels to guarantee compliance with ROHS environmental directives.
- Sample Evaluation: 👇 Request pre-production samples to validate the 6000K-7000K color temperature consistency against your specific housing materials.
- Handling: Ensure storage in a dry cabinet to maintain MSL 3 integrity.
❓ FAQ
Q: What is the forward current required for the XL-3020UWC?
A: The typical test current is 20mA. The absolute maximum continuous forward current is 20mA; do not exceed this without proper heat sinking to avoid thermal rollover.
Q: Can I use this LED for outdoor lighting applications?
A: While the operating temperature supports -40°C to +85°C, this model is primarily categorized for Indoor and Commercial lighting. For outdoor use, ensure the IP rating of the final fixture protects the internal LED components from moisture ingress.
Q: What does "MSL 3" mean for my assembly process?
A: MSL 3 (Moisture Sensitivity Level 3) means the components are sensitive to moisture. They must be mounted within 168 hours (1 week) of opening the vacuum-sealed bag, or they must be baked at a specific temperature to drive out moisture before reflow soldering.
Q: What is the maximum soldering temperature allowed?
A: The maximum soldering temperature is 260°C for a duration not exceeding 6 seconds (manual soldering). For reflow, follow the profile: 255°C (Peak) for lead-free or 235°C (Peak) for leaded processes.
Q: What is the viewing angle of this LED?
A: The XL-3020UWC features a wide 120-degree viewing angle, making it suitable for area lighting and backlighting where broad light dispersion is required.
Q: How do I order a specific color temperature?
A: You must specify the bin code. For 6000K-6500K, use code UW8-10; for 6500K-7000K, use code UW11-10.
