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.

DRY PACKING

The reel is packed in an anti-humidity bag to protect
the devices from absorbing moisture during
transportation and storage.

Aluminum bag

20613

RECOMMENDED METHOD OF STORAGE

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.

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:

192 h at 40 °C + 5 °C/- 0 °C and < 5 % RH
(dry air/nitrogen) or

96 h at 60 °C + 5 °C and < 5 % RH for all device
containers or

24 h at 100 °C + 5 °C not suitable for reel or tubes.
An EIA JEDEC standard JESD22-A112 level 2a label

is included on all dry bags.

CAUTION

1. Shelf life in sealed bag 12 months at <40°C and < 90% relative humidity (RH)

2. After this bag is opened devices that will be subjected to infrared reflow,
vapor-phase reflow, or equivalent processing (peak package body temp.

260°C) must be:

a) Mounted within
b) Stored at <1

3. Devices require baking before mounting if:
a) Humidity Indicator Card is >10% when read at 23°C +
b) 2a or 2b is not met.

4. If baking is required, devices may be baked for:

192 hours
96 hours
24 hours
