❓ FAQ
Q: What is the maximum forward current for the XL-1606UBC during operation?
A: The maximum continuous forward current is 20 mA. However, a pulse peak current of up to 80 mA is permissible, provided the pulse width does not exceed 0.1ms and the duty cycle remains ≤ 1/10.
Q: How is the brightness sorted for this specific LED model?
A: XINGLIGHT uses a brightness grading system where code "D2" represents 80–120 mcd and ranges up to code "D8" for 270–300 mcd at 20 mA. This helps engineers manage luminous uniformity in their applications.
Q: Is this LED suitable for lead-free reflow soldering processes?
A: Yes, the XL-1606UBC is compatible with lead-free soldering. The maximum recommended soldering temperature is typically limited to 260°C for ≤6 seconds for manual soldering, or standard profiles (Max 255°C) for reflow.
Q: What are the storage limitations to prevent moisture damage?
A: The component is classified at Moisture Sensitivity Level (MSL) 3. If the moisture barrier bag is opened, components should be mounted within 168 hours (7 days) at 30°C and 60% Relative Humidity to avoid pop-corning during reflow.
Q: What is the forward voltage range required to drive this LED?
A: The forward voltage (VF) varies between 2.7V and 3.3V at a test current of 20 mA. Designers should utilize these limits to calculate appropriate resistor values for constant voltage drivers.
