TSOP18..Vishay TelefunkenOzone Depleting Substances Policy StatementIt is the policy of Vishay Semiconductor GmbH to1. Meet all present and future national and international statutory requirements.2. Regularly and continuously improve the performance of our products, processes, distribution and operatingsystems with respect to their impact on the health and safety of our employees and the public, as well as theirimpact on the environment.It is particular concern to control or eliminate releases of those substances into the atmosphere which are known asozone depleting substances (ODSs).The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs andforbid their use within the next ten years. Various national and international initiatives are pressing for an earlier banon these substances.Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use ofODSs listed in the following documents.1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the EnvironmentalProtection Agency (EPA) in the USA3. 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 depletingsubstances 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 applicationby the customer. Should the buyer use Vishay-Telefunken products for any unintended or unauthorized application, thebuyer shall indemnify Vishay-Telefunken against all claims, costs, damages, and expenses, arising out of, directly orindirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.Vishay Semiconductor GmbH, P.O.B. 3535, D-74025 Heilbronn, GermanyTelephone: 49 (0)7131 67 2831, Fax number: 49 (0)7131 67 2423Document Number 82047Rev. 13, 13-Sep-00www.vishay.com7 (7)
