ROHM Semiconductor

- ROHM was established in Kyoto, Japan, in 1958. ROHM designs and manufactures semiconductors, integrated circuits and other electronic components. These components find a home in the dynamic and ever-growing wireless, computer, automotive and consumer electronics markets. Some of the most innovative equipment and devices use ROHM products.

ROHM's presence in the North American market continues to expand with a logistic headquarters in San Diego, California, a design center in San Jose, California, a QA Center in Novi, Michigan, a sales office in Guadalajara, Mexico and a sales network that covers marketing, sales, and engineering support for the North and South American clients from Canada to Brazil. In addition to a direct sales force, ROHM enjoys the collaboration of several sales-representative organizations and industry leading electronics distributors.
