Hermetically Sealed Aluminum Electrolytic Capacitors

Cornell Dubilier Knowles introduces its Slimpack, type MLSH, the first in a series of hermetically sealed aluminum electrolytic capacitors that Cornell plans to introduce over the next several months. With its glass-to-metal seal that prevents dry-out, this capacitor technology has 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 Cornell has been supplying to military and aerospace customers for more than 20 years. Cornell expects this technology to replace parallel and series banks of wet tantalum capacitors for new and existing designs, especially where bulk storage is paramount. The MLSH Slimpack measures 1.0” x 1.5” x 0.5”, weighs less than equivalent wet tantalum, and will have more capacitance than a parallel bank of three or more wet tantalum capacitors at -55 °C. High capacitance at a low temperature is a key requirement for power supplies used in military and aerospace applications.
