75 Years of Innovation

Bourns® Letters of Recognition: from Arrow, TTI, RS, Bürklin, MBS, and Anglia.

Seventy-five years ago, co-founders Marlan and Rosemary Bourns set up shop in their tiny 384 square-foot garage in Altadena, California. Their idea to provide a component solution to accurately determine an aircraft's pitch attitude solved a crucial problem for pilots. Their invention of the first miniature linear motion and vane position potentiometers propelled the Bourns' small start-up into the global corporation it is today. What started from the development of a single product, Bourns, Inc. is now known as a trusted innovator and manufacturer of a wide range of advanced products that are used in thousands of electronics industry applications.

From its earliest days, the founders established a benchmark for quality, value and innovation. In 1952, Marlan Bourns patented the world's first trimming potentiometer, trademarked Trimpot®, which remains the industry standard. Bourns now holds more than 91 patents, and that inventive spirit and dedication to excellence is still strong today. With a culture and processes that ensure continuous improvement and outstanding customer service, the company excels at meeting design requirements and satisfying international standards for a broad variety of applications in the automotive/vehicle, industrial, energy, consumer, computer, telecommunications, instrumentation, audio and low/medium risk* medical markets.

The college has become nationally recognized for its center for environmental research and technology and for its programs in chemical engineering and computer science. The Bourns family and employees also support numerous community outreach programs, green initiatives, scholarship opportunities and educational advancement such as the sponsorship of events to further education in science, technology, engineering and math (STEM) fields.
