Hermetically Sealed Aluminum Electrolytic Capacitors Introduced  


LIBERTY, S.C.—Cornell Dubilier Electronics, Inc. (CDE) has introduced its Slimpack, type MLSH, the first in a series of hermetically sealed aluminum electrolytic capacitors that the company plans to introduce over the next several months. With its glass-to-metal seal that is said to prevent dry-out, the capacitor technology is reported to have “extraordinarily long life to meet the most demanding applications for military and aerospace.”

The hermetic Slimpack is a spin-off of the non-hermetic Flatpack series that the company has been supplying to military and aerospace customers for more than 20 years. The company expects this technology to replace parallel and series banks of wet tantalum capacitors for new and existing designs, especially where bulk storage is paramount.

According to the company, the MLSH Slimpack, measuring 1.0 inch x 1.5 inch x 0.5 inch, will weigh less and have more capacitance than a parallel bank of three or more wet tantalum capacitors as at -55 °C. High capacitance at low temperature is a key requirement for power supplies used in military and aerospace applications.

In addition to its performance advantages at low temperature, the technology is expected to have a significantly lower cost than a comparable bank of wet tantalum capacitors.

Cornell Dubilier Electronics (cde.com) provides components for inverters, wind and solar power, electric vehicles, power supplies, motor drives, HVAC equipment. Its components are also used in motors, welding, aerospace, telecom, medical equipment, and UPS systems. The company has ISO-9001 certified manufacturing and distribution facilities in Liberty, South Carolina; New Bedford, Massachusetts; Mexicali, Mexico; and Hong Kong.
