LIBERTY, S.C.—Cornell Dubilier Electronics, Inc. (CDE) has announced significantly higher voltage values for its MLSH Slimpack series of hermetically sealed aluminum electrolytic capacitors. The components are said to have a true glass-to-metal seal that prevents dry-out of the capacitor electrolyte. As a result, they provide long life (5,000 hours) to “more than meet” the most demanding applications for military and aerospace, the company reported in a press release. They are now available in nine values, from 120 µF to 3,200 µF, with ratings up to 250 Vdc.
The hermetic Slimpack is an offshoot of the well-established non-hermetic Flatpack series. The new MLSH Slimpack can be used as a replacement for parallel and series banks of wet tantalum capacitors for new and existing designs. This change is especially beneficial where bulk storage is paramount, according to the manufacturer. The MLSH Slimpack devices measure 1.0 inch x 1.5 inch x 0.5 inch, weigh less, and have more capacitance than a parallel bank of three or more wet tantalum capacitors. High rated capacitance is maintained at temperatures as low as -55 °C, a key requirement for power supplies used in military and aerospace applications. Top-end temperature rating is 125 °C.
