📦 Package, Dimensions & Assembly Notes
The XL-1608 utilizes a compact, low-profile package designed for high-speed SMT placement. Its outline dimensions are 1.6x0.8x0.4mm. It is compatible with standard infrared reflow soldering processes for both leaded (max temp 235°C) and lead-free (max temp 255°C) assembly. The component has a Moisture Sensitivity Level (MSL) of 3 and is packaged according to EIA standards to ensure stability and reliability during automated manufacturing.
🔍 Sourcing & Supply Considerations
- Binning is Critical: The XL-1608 is supplied with brightness (D3-D7), voltage (M18-9 to M19-6), and wavelength (HB04-HB06) binning to ensure performance consistency.
- Authenticity Verification: Source from authorized XINGLIGHT distributors to guarantee compliance with RoHS and MSL requirements.
- Production Support: For high-volume orders, confirm lead times and support for automated tape-and-reel packaging.
❓ FAQ
Q: What is the purpose of the brightness, voltage, and wavelength binning for the XL-1608? A: The binning process (e.g., D3-D7 for brightness) allows manufacturers to select LEDs with consistent optical and electrical characteristics. This is crucial for applications where uniformity is required, such as backlights or indicator panels, ensuring product quality and reducing the need for manual sorting during production.
Q: What is the Moisture Sensivity Level (MSL) and why is it important? A: The XL-1608 has an MSL of 3. This indicates it is moderately sensitive to moisture and must be baked before reflow soldering if exposed to ambient conditions for an extended period. Adhering to MSL guidelines prevents "popcorning" or internal damage during the high-temperature soldering process.
Q: Is the XL-1608 suitable for both leaded and lead-free SMT processes? A: Yes. The device is designed to withstand the thermal profiles of both standard leaded and modern lead-free (RoHS-compliant) infrared reflow soldering processes, as specified in the guideline section of the datasheet.
Q: How does the XL-1608's viewing angle of 120° affect its application? A: A 120° viewing angle provides wide light dispersion, making the LED ideal for applications requiring broad illumination or where the viewing position is not fixed. This is beneficial for status indicators, backlights for buttons, and general-purpose lighting where a narrow beam is not required.
Q: Can I use the XL-1608 as a direct replacement for another 0603-size LED? A: While the physical footprint (1.6x0.8mm) is standard for a 0603 package, a direct replacement requires verification of all electrical and optical parameters, including forward voltage, luminous intensity, and wavelength binning, to ensure it meets the specific requirements of the circuit and application.
