Note

(1) Driving LED in reverse direction is suitable for short term application

Notes

(1) In one packing unit IVmax./IVmin. > 1.6

(2) Forward voltages are tested at a current pulse duration of 1 ms and a tolerance of ± 0.05 V

(3) Wavelengths are tested at a current pulse duration of 25 ms and an accuracy of ± 1 nm

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 in any one reel.



In order to ensure availability, single wavelength groups will not

be orderable.
