ROHM brand introduction

In depth analysis of ROHM brand
Brand background and historical evolution
ROHM was founded in 1958 and is headquartered in Kyoto, Japan. It is a leading global manufacturer of semiconductors and electronic components. The company initially focused on resistor production, successfully developed thin-film resistor technology in 1967, achieved mass production of transistors in 1969, and gradually expanded to the field of integrated circuits. In the 1970s, Rom further strengthened its strength in the field of analog semiconductors by acquiring Sanyo Electric's semiconductor division. In the 1980s, the company began its global expansion by establishing branches in the United States and Europe, and was listed on the Japanese Stock Exchange in 1994.
