Bourns has been leading the industry as a top manufacturer of quality potentiometers, circuit protection devices and semiconductors with a huge selection of parts. For over sixty years, Bourns has been providing engineering professionals in the portable, automotive, medical, consumer telecommunications and industrial spaces with quality solutions.

When founders, Marlan and Rosemary Bourns, began working in their tiny garage in Riverside, CA, in 1947, they could not have envisioned that their products would someday be found in automobiles, cellular telephones, notebook computers, implanted x-ray sensors for cancer treatment and even in a vehicle on Mars. With the 1952 introduction of the Trimpot® line, the world’s first patented trimming potentiometer, Bourns established a benchmark for quality, value and innovation for the rest of the industry to follow.
