Cornell Dubilier
Cornell Dubilier was founded in 1909 by William Dubilier who formed the company after he first used a glassy mineral called mica to help form a “condenser” (now called a “capacitor”). While the mica capacitor saw limited success for its intended application, it went on to revolutionize radio broadcast communications
allowing for better transmission over longer distances.

Soon after inventing the mica capacitor, Dubilier started manufacturing capacitors and contributed to World War I by developing a system to detect submarines. The Dubilier Company was the earliest commercial manufacturer of capacitors, and in 1933, merged with Cornell Radio to form Cornell Dubilier Electronics (CDE).

Fueled by the rise of radio and television broadcasting, the company experienced phenomenal growth, and by 1966, possessed more than 350 patents in radio and electrical sciences. Over time, the company grew even more to become one of the largest capacitor makers in the world.

A privately held, American owned company, Cornell Dubilier Electronics has earned a global reputation for manufacturing quality, high-end capacitors. Almost all of the company’s capacitors are used in demanding industrial applications, separating themselves from the competition.

Even with the emergence of Asian sources, nobody can compete with Cornell Dubilier’s service and engineering. While Asian manufacturers can build the capacitor, CDE engineers have the technical knowledge to build a better capacitor based on R&D, budgets and a broad customer base. With manufacturing facilities in
North America, product support in the U.S., Mexico and China, and a distribution center in Massachusetts, Cornell Dubilier Electroinics is well positioned to help their customers energize ideas. They pride themselves in giving their customers an exciting solution that makes their product more reliable, longer lasting and
better suited for the application.
