Product Overview
The Cornell Dubilier MLPS/MLPSR series offers 105C Flatpack ultra-long-life, very low-profile aluminum electrolytic capacitors. Designed for high capacitance density in a compact form factor, these capacitors feature laser-welded seals and rugged construction for enhanced reliability and longevity. They are ideal for demanding applications including ruggedized, commercial, and military-grade power supplies. These capacitors have been rigorously tested to 10,000 hours at rated voltage and ripple current at 105C, providing military-grade performance optimized for high-temperature environments. Key advantages include excellent capacitance retention at low temperatures and resistance to "dry-out" compared to conventional electrolytics.
