The prospectus relates to the sale by certain of our security holders of up to $550,000,000 aggregate principal amount at maturity of the Liquid Yield Option Notes ("LYONs") of Vishay and the shares of common stock issuable upon conversion and/or our re-purchase of the LYONs.

Capitalized terms used in this prospectus supplement and not otherwise defined herein have the meanings specified in the prospectus. INVESTING IN THE LYONS INVOLVES RISKS THAT ARE DESCRIBED IN THE "RISK FACTORS" SECTION BEGINNING ON PAGE 10 OF THE PROSPECTUS.
