📌 Product Overview
The XL-4014UWC-02 is a surface-mount device (SMD) LED from XINGLIGHT, housed in a compact 4014 package (4.0x1.4x0.8mm). 💡 It utilizes a yellow colloid with a high-brightness white chip, engineered to provide a stable color temperature range of 7000K to 8000K.
Designed for modern automated assembly lines, this component complies with ROHS directives and is suitable for standard SMT processes. Its primary design focus is balancing luminous intensity with thermal management in constrained spaces, making it a viable candidate for dense light engine arrays.
🔌 Typical Applications
Based on its optical characteristics and form factor, the XL-4014UWC-02 is suitable for the following scenarios:
- Indoor Ambient Lighting: Ideal for LED tubes and rigid light strips where consistent cool-white illumination is required.
- Backlighting Systems: 💡 Designed for LCD backlight units requiring uniform light distribution with a 120-degree viewing angle.
- Commercial & Decorative: Supports advertising boards and metal plate hard light strips for architectural or accent lighting.
- Automotive Interiors: Suitable for auxiliary interior lighting where compact size and reliability are critical.

🚀 Sourcing & Supply Considerations
When integrating the XL-4014UWC-02 into your BOM, keep the following supply chain factors in mind:
- Binning Management: Verify voltage and luminosity bin codes with the supplier to ensure batch-to-batch consistency.
- Quality Assurance: Confirm compliance with ROHS directives and request reliability test data (e.g., 1000h operating life at room temp).
- Procurement Strategy: For mass production, evaluate the lead time for specific bin selections, as popular bins (e.g., J2/N13-4) may move faster.
- Verification: Always cross-check the packaging labels for the correct model number XL-4014UWC-02 upon receipt to prevent mix-ups with similar 4014 series LEDs.
❓ FAQ
Q: What is the maximum current I can drive the XL-4014UWC-02 with continuously?
A: The absolute maximum continuous forward current is 60mA. 💡 Exceeding this without proper heat sinking will likely degrade the LED lifespan or cause immediate failure.
Q: What does the "MSL 3" rating mean for my assembly process?
A: MSL 3 (Moisture Sensitivity Level) means the components can be exposed to the factory floor environment for up to 168 hours (one week) after opening the vacuum bag before they must be soldered. If stored longer, they require baking to prevent popcorning damage during reflow.
Q: Can I use this LED for outdoor lighting applications?
A: While the datasheet lists storage and operating temperatures up to +85℃, the IP rating depends on your final product housing. The LED itself is not waterproof but is suitable for internal fixtures of outdoor luminaires if properly enclosed.
Q: How do I interpret the Color Temperature (CCT) specs?
A: The CCT range is 7000K to 8000K. This is a "Cool White" light, appearing slightly blue. 💡 Ensure your application allows for this specific tint, as it differs from warm white (3000K) or neutral white (4000K) options.
Q: What is the forward voltage requirement for driving this LED?
A: At 60mA, the forward voltage (VF) ranges from 2.8V to 3.4V. Your driver circuit should be designed to accommodate this range, particularly when wiring multiple LEDs in series.
