Rugged aluminum electrolytic capacitors for defense and 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 1.5in, 2in, 2.5in or 3in. The 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 -55C is very strong, with excellent high temperature performance up to +125C. 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. With a profile of 1in x 0.5in, the MLSG Slimpack welded seals capacitors fit into the tightest of spaces and meet a DC test of 5,000 hours at rated voltage, 125C. The MLSG Slimpack is a perfect fit for defense and aerospace applications requiring a low profile, rugged design and long-life. It is also available in an HRMLSG type for high reliability burn-in – and is rated to vibration levels of 80g.
