Procurement Notes

Verify the specific suffix configuration against official Cree documentation to ensure correct wavelength and intensity binning. Confirm that the ordering code matches the required package type and lead-free compliance status. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high visibility in direct sunlight due to its UV-resistant encapsulation. Ensure the circuit design accommodates the 2.6 V forward voltage drop and 50 mA maximum current rating. Consider the 30-degree viewing angle and oval lens shape for optimal beam distribution in signage assemblies where standard round LEDs may not provide sufficient coverage.
