ð Sourcing & Supply Considerations
When integrating the XL-2835SURC-02 into your BOM, consider the following supply chain factors:
- Bin Selection: Verify specific brightness (E5-E8) and voltage (N12-7/8/9) grades to match your driver design.
- Authenticity: Source exclusively through authorized channels to guarantee ROHS compliance and MSL 3 ratings.
- Samples: Request samples prior to mass production to validate color binning and intensity in your specific optical assembly.
â FAQ
Q: What is the MSL level of the XL-2835SURC-02?
A: The moisture sensitivity level is MSL 3. This means the components can withstand floor life of up to 168 hours (one week) at 30â/60% RH after opening the vacuum-sealed bag before baking is required.
Q: Can this LED be used with a lead-free soldering process?
A: Yes, it is suitable for both leaded and lead-free infrared reflow processes. For lead-free, the peak temperature should not exceed 255â for 5-10 seconds.
Q: What does the "Water Clear Colloid" specification mean?
A: It refers to the transparent epoxy encapsulation. This ensures minimal light absorption and refraction, allowing the raw red light output to pass through efficiently.
Q: How is the brightness graded?
A: Brightness is divided into codes E5 through E8, ranging from 550 mcd to 900 mcd. Ensure you specify the required bin code to maintain uniformity in your lighting product.
Q: What is the maximum current I can drive continuously?
A: The absolute maximum continuous forward current is 60 mA. Exceeding this will likely degrade the LED junction rapidly or cause catastrophic failure.
Q: Is the XL-2835SURC-02 ROHS compliant?
A: Yes, the datasheet explicitly states that the product is an environmental protection product compliant with ROHS directives.
