📦 Package, Dimensions & Assembly Notes
The XL-302UGD is packaged in moisture-proof, anti-static foil bags to ensure protection during storage and handling. Key dimensions are F3/3.83.05.2*18mm, with a tolerance of ±0.50mm unless otherwise specified. For assembly, the solder joint must be at least 2.0mm from the bottom of the LED body to prevent damage. MSL rating is 2, requiring careful handling to avoid moisture-related failures.
🚀 Sourcing & Supply Considerations
- Available in brightness (B7-B9), voltage (N13-3 to N13-5), and wavelength (HG02-HG04) grades for precise BOM matching.
- RoHS-compliant and designed for high-volume production with stable supply chains.
- Verify authenticity through authorized distributors to avoid counterfeit risks.
❓ FAQ
Q: What is the brightness grading for the XL-302UGD?
A: The LED is graded by luminous intensity: B7 (4000-5000 mcd), B8 (5000-6000 mcd), and B9 (6000-8000 mcd) at IF=20mA.
Q: What are the soldering conditions for this LED?
A: Reflow soldering must be ≤240°C for ≤6s, while manual soldering requires 300°C for 3s. Maintain a 2.0mm distance from the LED body.
Q: Is this LED suitable for automotive applications?
A: Yes, it meets automotive reliability standards, including high-temperature and vibration tests, making it suitable for dashboard indicators and other automotive electronics.
Q: How should I store unused XL-302UGD LEDs?
