📏 Package, Dimensions & Assembly Notes
The XL-0201UYC utilizes a standard EIA-compliant tape and reel package for automated pick-and-place. Its ultra-compact dimensions (0.65x0.35x0.4mm) require precise stencil design for optimal solder paste deposition. It is classified as MSL 3, necessitating moisture-sensitive handling and baking procedures before SMT assembly to prevent pop-corning during reflow soldering.
🚀 Sourcing & Supply Considerations
- Ensure supply chain partners offer authentic, traceable XINGLIGHT components.
- Request samples for validation of brightness and voltage binning to match design requirements.
- Confirm lead times and MOQs for high-volume production to avoid BOM delays.
- Verify packaging compliance with your SMT line's feeder specifications.
❓ FAQ
Q: What are the brightness (Iv) grades for the XL-0201UYC? A: The LED is available in three brightness bins: D1 (80-120 mcd), D2 (120-150 mcd), and D3 (150-180 mcd), all tested at IF=20mA.
Q: How is the wavelength controlled for color consistency? A: Wavelength is graded into six codes (HY01 to HY06), each with a 2.5nm range from 580nm to 595nm, ensuring a tight ±1nm error for consistent yellow output.
Q: What is the Moisture Sensitivity Level (MSL)? A: The XL-0201UYC has an MSL rating of 3, requiring specific storage conditions and a baking process before reflow soldering to prevent internal damage.
Q: Is this LED suitable for automated SMT assembly? A: Yes, it is designed for compatibility with automatic mounters and standard reflow soldering processes, using EIA-standard tape and reel packaging.
Q: What is the recommended soldering profile? A: The peak soldering temperature must not exceed 260°C and the duration at this temperature should be ≤6 seconds, as specified in the Absolute Maximum Ratings.
