Packing
Dampproof packing
Products will be packed in anti-humidity aluminium bags to prevent the products from moisture absorption
during transportation and storage. Each bag contains a desiccant with moisture indicators. In the event bags
absorb moisture, the indicators change their color from blue to pink.
Recommended method of storage
Dry box storage is recommended to prevent the parts from moisture absorption. The following conditions
should be preserved if dry boxes are not available.
Storage temperature: 10 to 30°C Storage humidity: 60% RH max
In case of moisture absorption the device will recover to the former condition by drying under the following
recommended conditions:
Taped version: 60°C/ 48 h Untaped version: 60°C/ 48 h

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. V arious 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 Telefunken products for any unintended or unauthorized application, the
buyer shall indemnify Vishay Telefunken 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.
