❓ FAQ
Q: What is the MSL rating of the XL-1606UOC?
A: The XL-1606UOC has a Moisture Sensitivity Level (MSL) of 3. This means it can be exposed to a factory floor life of 168 hours before baking is required prior to reflow soldering.
Q: What are the binning codes for brightness and voltage?
A: Brightness is binned from D2 (80–120 mcd) to D6 (210–240 mcd). Forward voltage is binned from M17-9 (1.8–1.9V) to M18-5 (2.3–2.4V), allowing for precise selection based on power budget and optical requirements.
Q: Is this LED suitable for outdoor lighting applications?
A: While the datasheet lists "Indoor and outdoor lighting" as an application, designers must ensure the specific enclosure provides adequate ingress protection (IP rating) and environmental sealing, as the component itself is a standard open SMD.
Q: What is the maximum soldering temperature for this component?
A: The maximum soldering temperature is 260°C for a duration not exceeding 6 seconds. For infrared reflow, the peak temperature should not exceed 255°C (Lead-free) or 235°C (Leaded process).
Q: How does the viewing angle affect the design?
A: The XL-1606UOC has a typical viewing angle of 120°. This wide angle makes it suitable for indicator lights and backlight diffusion where uniform light spread is preferred over focused beams.
Q: What is the ESD tolerance?
A: The component features an antistatic ability of 2000V. Standard ESD precautions (wrist straps, grounded mats) should be observed during manual handling and assembly to prevent latent damage.
