Cornell Dubilier Electronics Inc Introduces its 381LL Series of Longlife Snapin Aluminum Electrolytic Capacitors

The 381/383LL snap-in series is targeted for use in critical applications where long life and reliability are paramount.

Liberty, SC – January 20, 2020 Cornell Dubilier Electronics, Inc. (CDE) introduces its 381LL series of long-life snap-in aluminum electrolytic capacitors. The series, designated with an expected life of 8,000 hours at full-rated conditions, demonstrates superb stability in capacitance and DC leakage current over time on test. The snap-in series is targeted for use in critical applications where long life and reliability are paramount.

Capacitance values range from 740µF to 100,000µF at working voltages of 16 to 250 WVDC with ripple current ratings up to 10 Amps @ 105 °C. The snap-in series is available in two pin configurations in the smaller diameters with 4 and 5 pin options in the larger diameters.

General applications include any circuit requiring high capacitance with low ESR, high ripple current and long life.  This includes switch-mode power supplies, UPS systems, solar and other high-power inverters. 

CDE’s 381LL, long-life aluminum electrolytic capacitors are available from the company’s franchised distributors.

 

About Cornell Dubilier Incorporated

Cornell Dubilier’s roots can be traced back to 1909 when founder William Dubilier 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.

 

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 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 Global Leader

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.
