Cornell Dubilier Announces Availability of its Type RA Multilayered Film Capacitors

Cornell Dubilier announces availability of its Type RA multilayered film capacitors for 125 °C operation. Type RA capacitors are constructed using stacked metallized polyester protected with an impregnated sealant, which eliminates the need for an external case. This package style offers the highest energy density technology available for switching power supplies, DC to DC converters and other high ripple current applications.

Type RA capacitors are impregnated with a microcrystalline polymer sealant and exterior tape wrap that protects the capacitor element from moisture, allowing it meet 85 °C/ 85% RH requirements for demanding applications in military vehicles and aerospace.

Available in capacitance values ranging from 0.1 µF to 10.0 µF, voltage ratings of 100, 250, 400 and 500 Vdc, Type RA capacitors are terminated with radial leads to cover a broad range of applications in power electronics where high density capacitors are needed for board-level DC filtering.

Cornell Dubilier RA capacitors series are available through our key franchised distributor sites for quick turnaround on prototype and preproduction quantities.

Since its founding in 1909, Cornell Dubilier has been dedicated to advancing capacitor technology for new applications. The company combines innovative products with engineering expertise to provide reliable solutions for inverters, wind and solar power, electric vehicles, power supplies, motor drives, HVAC, motors, welding, aerospace, medical equipment, telecom and UPS systems.
 

About Cornell

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.

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.
