📏 Package, Dimensions & Assembly Notes
The XL-B324SURUGW utilizes a compact F3 package with dimensions of 3.8 x 3.0 x 5.2mm. It is packaged according to EIA standard specifications for automated handling. For manual soldering, the temperature must not exceed 300°C for 3 seconds, with the soldering point kept a minimum of 3.5mm from the base of the LED body to prevent damage.
📈 Sourcing & Supply Considerations
- Binning Codes: Critical for color consistency (wavelength), brightness (mcd), and forward voltage (V) matching.
- MSL Level: Moisture Sensitivity Level 2-3 requires strict dry storage and baking procedures before SMT reflow.
- Supply Chain: Authenticity verification is essential to avoid counterfeit components that may fail reliability tests.
- Documentation: Request the full datasheet and reliability test reports for production validation.
❓ FAQ
Q: What do the brightness and voltage grading codes (e.g., A6, N12-9) mean?
A: These codes define specific binning ranges for luminous intensity (A5-A6 for Red, B3-B6 for Green) and forward voltage (N12-7 to N12-9 for Red, N13-3 to N13-5 for Green), ensuring batch-to-batch consistency for your application's requirements.
Q: Is this LED suitable for high-temperature automotive environments?
A: Yes, its operating temperature range of -20°C to +85°C makes it suitable for many automotive interior applications, provided it is operated within its absolute maximum ratings.
Q: What is the recommended soldering process for this component?
A: For reflow soldering, use a peak temperature of 240°C for a maximum of 6 seconds. For manual soldering, limit the temperature to 300°C for 3 seconds, ensuring the solder joint is at least 3.5mm from the LED body.
Q: How does the MSL rating impact production?
A: The MSL 2-3 classification means the component is moderately sensitive to moisture. It must be stored in a dry environment and may require a pre-surf bake before reflow soldering to prevent internal delamination or popcorning.
Q: Can this LED be used for outdoor general lighting?
A: While its specifications support general lighting, its IP rating is not specified. It is more commonly used for indoor or protected applications like signal indication and backlighting.
Q: What are the key differences between the red and green electrical characteristics?
A: The green LED has a significantly higher luminous intensity (2100-4000 mcd vs. 400-700 mcd) and a higher forward voltage (2.8-3.4V vs. 1.8-2.4V), requiring different drive circuit design considerations.
