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

Dry box storage is recommended as soon as the aluminum
bag has been opened to prevent moisture absorption. The
following conditions should be observed, if dry boxes are
not available:
• Storage temperature 10 °C to 30 °C
• Storage humidity ≤ 60 % RH max.
E
F
G H I
K

M
After more than 672 h under these conditions moisture
content will be too high for reflow soldering.
In case of moisture absorption, the devices will recover to
the former condition by drying under the following condition:
A. 2D barcode
B. Part No: Vishay part number
192 h at 40 °C + 5 °C / - 0 °C and < 5 % RH (dry air /
