Note

(1)

Driving the LED in reverse direction is suitable for a short term application

Note

• Luminous intensity is tested at a current pulse duration of 25 ms and an accuracy of ± 11 %.



The above type numbers represent the order groups which include only a few brightness groups. Only one group will be shipped on each

reel (there will be no mixing of two groups on each reel).



In order to ensure availability, single brightness groups will not be orderable.



In a similar manner for colors where wavelength groups are measured and binned, single wavelength groups will be shipped on any one reel.



In order to ensure availability, single wavelength groups will not be orderable.
