S852TF Vishay Semiconductors Silicon NPN Planar RF Transistor Description 1 The main purpose of this bipolar transistor is broadband amplification up to 2 GHz. In the space-saving 3-pin surface-mount SOT-490 package electrical performance and reliability are taken to a new level covering a smaller footprint on PC boards than previous packages. In addition to space savings, the SOT-490 provides a higher level of reliability than other 3-pin packages, such as more resistance to moisture. Due to the short length of its leads the SOT-490 is also reducing package inductances resulting in some better electrical performance. All of these aspects make this device an ideal choice for demanding RF applications. 2 3 16867 Electrostatic sensitive device. Observe precautions for handling.

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.
