Flatpack and Slimpack Capacitors with 5,000 hours operating life.

Press Release Summary:

Applied in compact power supplies like military and aerospace systems, MLSG Flatpack and Slimpack Capacitors measure 0.5” thick and 1.75” wide and 0.5 in thick by 1 in wide respectively. Flatpack welded seals capacitors can withstand up to 50g vibrations and altitudes greater than 80,000 ft. Flatpack capacitors are offered in values 220µF to 24,000µF and Slimpack from 120µF to 3,200µF, both are rated at 250VDC.

New Yorker Electronics Releases New CDE Rugged Critical Systems Capacitor Delivering 5,000-Hour Life at 125°C

MLSG Series of Cornell Dubilier Flatpack and Slimpack Ruggedized Aluminum Electrolytic Capacitors with Welded Seals, Geared to Military & Aerospace

New Yorker Electronics has introduced the latest in a series ruggedized aluminum electrolytic capacitors with welded seals from Cornell Dubilier Electronics (CDE), the MLSG in both Flatpack and Slimpack. This series targets compact power supply applications in military and aerospace, as well as other critical systems. Design enhancements and a new electrolyte push the MLSG to nearly double the operating life of its predecessor, the MLSH, at no added cost.

Two principal package profiles are offered in this technology, the MLSG Flatpack which measures just 0.5in thick and 1.75in wide and the MLSG Slimpack measuring 0.5in thick by 1in wide, both offered in lengths of 1.5, 2, 2.5 or 3 inches.

MLSG Flatpack welded seals capacitors can be made to withstand up to 50g vibrations (10g standard) and altitudes greater than 80,000 feet. With stainless steel cases and near hermetic welded seals, they are built for extended duty in very harsh conditions. Especially noteworthy is that a high level of performance is maintained over the full operating temperature range. Capacitance retention at -55°C is very strong, with excellent high temperature performance up to +125°C. The new electrolyte system is fully REACH compliant, allowing application of the components in a broad range of applications where space efficiency and extraordinarily long life are required.

A wide range of standard capacitance values from 220µF to 24,000µF are available, with voltage ratings up to 250VDC. The unique flat package design does more than save space. It is easily cooled, and can offer unique flexibility in ganging two or more devices in ways that conventional electrolytics can’t. 

Options include High Vibration (HVMLSG), for performance to 50g, and High Reliability (HRMLSG), with burn-in at rated voltage and 85°C. Where a true glass-to-metal hermetic seal is required, CDE offers the MLSH Slimpack, which is similarly constructed in a flat stainless steel package. It is available in nine values, from 120µF to 3,200µF, with ratings up to 250VDC.

With a profile of 1in x .5in, the MLSG Slimpack welded seals capacitors fit into the tightest of spaces and meet a DC test of 5,000 hours at rated voltage, 125°C. MLSG Slimpack is a perfect fit for military and aerospace applications requiring a low profile, rugged design and long-life. The MSGL Slimpack is also available in an HRMLSG type for high reliability burn-in – and is rated to vibration levels of 80g.
