❓ FAQ
Q: What is the MSL level of the XL-2835VRC-02? A: The moisture sensitivity level is 3. This means the components must be mounted within 168 hours (1 week) of opening the vacuum-sealed bag. If floor life is exceeded, baking is required to prevent popcorning damage during reflow.
Q: Can this LED be used at 60mA continuously? A: Yes, the datasheet specifies 60mA as the Max Continuous Forward Current. However, thermal management is critical. Ensure the PCB has sufficient copper area to dissipate heat, keeping the junction temperature within the -40°C to +85°C operating range.
Q: What is the difference between the H6 and H7 brightness codes? A: These are brightness (luminous intensity) bins. H6 covers 8-10 Lumens, while H7 covers 10-13 Lumens (at 60mA). Selecting the correct bin ensures uniform brightness across your light fixture.
Q: Is the XL-2835VRC-02 compatible with lead-free soldering? A: Yes, it is suitable for both lead and lead-free processes. For lead-free soldering, the peak temperature should not exceed 255°C, with specific time constraints maintained above 217°C (60-120 seconds).
Q: What does the "HR02" and "HR03" marking mean? A: These refer to the Dominant Wavelength bins. HR02 is 620-625nm, and HR03 is 625-630nm. Using a single bin code in a production batch is essential for visual color consistency in the final product.
