Product Overview
The Cornell Dubilier MLPS/MLPSR series are 105C Flatpack ultra-long life, very low profile aluminum electrolytic capacitors designed for high capacitance density in a compact package. Featuring laser-welded seals and rugged construction, these capacitors offer extraordinary long-life and reliability, making them suitable for ruggedized, commercial, and military-grade power supplies. They are fully tested to 10,000 hours at rated voltage and ripple current at 105C, providing military-grade performance optimized for demanding applications. Key advantages include high vibration resistance (up to 20g with HV option), excellent capacitance retention at low temperatures, and resistance to "dry-out" thanks to their welded seal.
