<i> Electronica 2006 UPDATE</i>: 01.11.2006<br><b>Vishay to Present Broad Range of Product Demonstrations</b>

MALVERN, PENNSYLVANIA—November 7, 2006

Vishay Intertechnology, Inc. (NYSE: VSH) will be presenting over two dozen different product demonstrations at the electronica 2006 show, to be held November 14 – 17 at the New Trade Fair Center in Munich, Germany. The demonstrations will highlight performance characteristics of a number of Vishay discrete semiconductors and passive electronic components. The electronica trade show, held every two years in Germany, presents the world’s largest range of electronic components and application-oriented assemblies. Vishay will be participating at electronica 2006 with exhibits at four locations within the New Trade Fair Center:

Main Booth: A5.143 Solutions Booth: A5.142? Automotive Innovation Booth: A6.A55? Wireless Communications Booth: A4.W14

"Vishay’s product demonstrations are an essential part of our presence at electronica 2006," stated Dr. Felix Zandman, Vishay’s Chairman and Chief Technical and Business Development Officer. "They use key technical criteria to show how Vishay components, a number of which utilize patented or industry-best technology, outperform competing components. As a group, our product demonstrations indicate the breadth and depth of Vishay’s extensive product portfolio, which is one of the industry’s broadest."

All Vishay product demonstrations will be held at electronica’s Main Booth (A5.143), except for the demonstration of Vishay’s wireless JetWeigh-W™ Aircraft Weighing System at Booth A4.W14. Below is a complete list of the demonstrations:
