| TLVH4201 Vishay Telefunken Backlighting LED in o 3 mm Tinted Non-Diffused Package Color High efficiency red Type TLVH4201 Technology GaAsP on GaP Angle of Half Intensity o 85 Description The TLVH4201 series was developed for backlighting. Due to its special shape the spatial distribution of the radiation is qualified for backlighting. To optimize the brightness of backlighting a custom- built reflector (with scattering) is required. Uniform illumination can be enhanced by covering the front of the reflector with diffusor material. This is a flexible solution for backlighting different areas. 96 11664 Features D D D D D D D D High light output Wide viewing angle Categorized for luminous flux Tinted clear package Low power dissipation Low self heating Rugged design High reliability Applications Backlighting of display panels, LCD displays, symbols on switches, keyboards, graphic boards and measuring scales Illumination of large areas e.g. dot matrix displays Document Number 83100 Rev.

A1, 04-Feb-99 TLVH4201 Vishay Telefunken 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-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.
