Designed to stand up to the rigors of battle, CDE’s MLS Series of stainless steel Flatpack capacitors now handle up to 50 g’s of vibration. Vigorously tested in-house to the toughest military and industry standards, Flatpack capacitors are not only rugged, their flat form factor also allows you to fit them into tight spots, cool them, and easily gang them for compact, high bulk storage. Their precision welded construction provides a near hermetic seal that you can bank on up to 80,000 feet.

MLP Flatpack - The MLP delivers up to 20 joules of energy storage in a 1/2" height with 50 years life at +45°C. You can readily heatsink it to double the ripple current capacity. The MLP is the square-peg component that fits the square-holes in electronic assemblies. The MLP's (85°) high-energy storage and box-shape make it perfect for voltage holdup or filtering in military SEM-E modules, telecom circuit packs and computer cards.

MLS Flatpack - The MLS is perfect for hi-rel military systems and applications operating above 85°C. It has 100 years expected operating life and can withstand more than 80,000 feet altitude. The MLS (125°) extends the super performance of the MLP from a maximum operation temperature of 85°C to 125°C. The MLS incorporates a rugged, stainless steel case which assures flatness to beyond 125°C and is perfect for hi-rel military systems and applications operating above 85°C.
