Product Overview
The MLPS/MLPSR series by Cornell Dubilier are 105C Flatpack ultra-long life, very low profile aluminum electrolytic capacitors. Designed for high capacitance density in a compact package, these capacitors offer extraordinary long-life and reliability suitable for ruggedized, commercial, and military-grade power supplies. They feature laser-welded seals that resist "dry-out" and have been fully tested to 10,000 hours at rated voltage and ripple current at 105C. Key advantages include military-grade construction optimized for 105C operation, high vibration resistance (up to 20g with HV option), and excellent capacitance retention at -55C.
