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
