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 and an accuracy of 1 nm.

DRY PACKING The reel is packed in an anti-humidity bag to protect the devices from absorbing moisture during transportation and storage.
LEVEL This bag contains MOISTURE -SENSITIVE DEVICES
CAUTION
2a
1. Shelf life in sealed bag 12 months at <40C 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. 260C) must be: a) Mounted within 672 hours at factory condition of < 30C/60%RH or b) Stored at <10% RH. 3. Devices require baking before mounting if: a) Humidity Indicator Card is >10% when read at 23C + 5C or b) 2a or 2b is not met. 4. If baking is required, devices may be baked for: 192 hours at 40C + 5C/-0C and <5%RH (dry air/nitrogen) or o or 96 hours at 605 Cand <5%RH For all device containers 24 hours at 1005C Not suitable for reels or tubes

Example of JESD22-A112 level 2a label ESD PRECAUTION Proper storage and handling procedures should be followed to prevent ESD damage to the devices especially when they are removed from the antistatic shielding bag. Electro-static sensitive devices warning labels are on the packaging. VISHAY SEMICONDUCTORS STANDARD BAR CODE LABELS The Vishay Semiconductors standard bar code labels are printed at final packing areas. The labels are on each packing unit and contain Vishay Semiconductors specific data.
FINAL PACKING The sealed reel is packed into a cardboard box. A secondary cardboard box is used for shipping purposes. RECOMMENDED METHOD OF STORAGE Dry box storage is recommended as soon as the aluminium 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.

OZONE DEPLETING SUBSTANCES POLICY STATEMENT It is the policy of Vishay Semiconductor GmbH to 1. Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances.
We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay Semiconductors products for any unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
