EE Times' Top 100 Systems OEMs includes the companies that our editors have identified as the key integrators in the business — the state-of-the-art users of the components and devices that make up the electronics industry. The Top 100 lists some of the major customers of the power supplies, connectors, ICs and software developed by such non-Top 100 companies as AMD, AMP and Lambda. Texas Instruments Inc. and National Semiconductor Corp. are among the companies that aren't on the list, but both recently divested their systems divisions to concentrate on semiconductors and components. Suppliers such as Intel Corp. and Microsoft Corp each hold places on the list because they have major systems units.
