More than sixty 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 method of accurately determining an aircraft's pitch attitude solved a crucial problem for pilots. The invention of the first miniature linear motion and vane position potentiometers propelled their tiny business into a global corporation, manufacturing a range of products that impact almost every aspect of today's electronics industry.

    From its earliest days, Bourns established a benchmark for quality, value, and innovation. In 1952, Bourns patented the world's first trimming potentiometer, trademarked Trimpot .. Bourns' dedication to excellence ensures continuous improvement of its products and services to satisfy customer requirements on a global basis.

    The company, with worldwide headquarters in Riverside, California and nine other facilities around the world has continued growing through acquisitions and start-ups. Product lines now include precision potentiometers, panel controls, encoders, resistor/capacitor networks, chip resistors/arrays, inductors, transformers, resettable fuses, thyristor-based overvoltage protectors, line feed resistors, gas discharge tubes, telephone station protectors, 5-pin protectors, industrial signal, irrigation and petroleum protectors, CATV coax protectors, signal data protectors, indoor and outdoor POT splitters, network interface devices, and integrated circuits.

    Bourns, Inc. serves a broad range of markets, including telecommunications, computer, industrial, instrumentation, automotive, consumer, audio, and medical.
