Growth and Prosperity
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 (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 Global Leader
Cornell Dubilier 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.
No Substitute For Experience
Even with the emergence of Asian sources, nobody can compete with Cornell Dubilier’s service and engineering. While Asian manufacturers can simply build the capacitor, CDE engineers have the technical knowledge to build a better capacitor based on R&D, budgets, and a broad customer base. After all, the more applications engineers have seen, the better they are at building capacitors.
A Look Toward the Future
In 2023, Cornell Dubilier was acquired by Knowles Corporation. The acquisition expands Knowles' portfolio of high-performance ceramic capacitors to include film, electrolytic, mica and supercapacitors. Together, Knowles and Cornell Dubilier will be able to offer more cutting-edge products and solutions to customers.
