📌 Product Overview
The XL-2214UGC is a compact surface-mount device (SMD) LED designed by XINGLIGHT for high-density lighting applications. 💡 Housed in a miniature 2.2x1.4x1.35mm package with a transparent colloid, it emits efficient green light (525nm typical). This component is specifically engineered for automated SMT production, offering a balance of luminosity and space efficiency. Designers should focus on its robust thermal performance and compatibility with infrared reflow soldering to ensure assembly reliability.
🚀 Typical Applications
Based on its optical characteristics and compact footprint, the XL-2214UGC is suited for:
- Commercial & Indoor Lighting: Ideal for downlights and accent fixtures where board space is limited.
- Automotive Interiors: Suitable for dashboard illumination and soft ambient lighting.
- LCD Backlighting: Provides consistent color for small-to-medium display panels.
- Signage & Flexible Strips: Perfect for advertising light boxes and decorative flexible strips due to its low profile.
- Status Indicators: Effective for device status lights and HMI feedback.

📦 Package, Dimensions & Assembly Notes
- Dimensions: The compact body size is 2.2mm (L) x 1.4mm (W) x 1.35mm (H). Tolerance is typically $\pm0.25\text{mm}$ unless noted.
- Packaging: Supplied in EIA standard compliant tape and reel for automated pick-and-place.
- Soldering:
- Reflow: Designed for infrared reflow processes. Do not exceed 2 reflow cycles.
- Hand Soldering: Only for repair. Use iron $<30\text{W}$, tip temp $<300^\circ\text{C}$, for $<3$ seconds per pad.
- Moisture Sensitivity: Classified as MSL 3. Ensure proper baking before assembly if exposed to ambient moisture for extended periods.
🛒 Sourcing & Supply Considerations
- Bin Selection: Verify specific Brightness (F5-F8) and Voltage (N13-3 to N13-5) codes required for your design to ensure batch consistency.
- Authenticity: Source exclusively through authorized XINGLIGHT channels to guarantee ROHS compliance and reliability standards.
- Sample Evaluation: Always request samples from the specific production batch before mass production to verify color and intensity matching.
- Lead Time: Check stock availability for high-demand bins like F7/F8 to avoid production delays.
❓ FAQ
Q: What is the forward voltage range for this LED? A: The typical forward voltage is between 2.8V and 3.4V when driven at 20mA. Designers should account for the maximum 3.4V when calculating driver circuit headroom to ensure consistent brightness across all bins.
Q: Can this component be used for flexible light strips? A: Yes, its low height (1.35mm) and 2214 footprint make it ideal for flexible strips and tight spaces where larger 3528 or 5050 packages will not fit.
Q: What are the storage requirements to prevent damage? A: The storage temperature range is -40°C to +85°C. Crucially, it has a Moisture Sensitivity Level (MSL) of 3. If the packaging has been opened, baking may be required prior to reflow soldering to prevent "popcorning" or delamination.
Q: How should I handle repair soldering? A: Hand soldering is discouraged for production but acceptable for repair. Use a soldering iron under 30W with a tip temperature below 300°C. Do not solder the same terminal more than once and limit duration to 3 seconds maximum.
Q: What is the viewing angle? A: The XL-2214UGC features a wide viewing angle of 120 degrees, making it suitable for general lighting and backlighting where broad light dispersion is needed rather than a focused spot.
