Note

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

Note

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

≤ 1.6

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

Note

• Wavelengths are tested at a current pulse duration of 25 ms
