Note
• Not designed for reverse bias
Note
• Luminous flux 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
• Chromaticity coordinate groups are tested at a current pulse direction of 25 ms and a tolerance of ± 0.01.
