Product Description
Product Overview
The CDM Cornell Dubilier MLPS/MLPSR series are 105C Flatpack ultra-long life, very low profile aluminum electrolytic capacitors. Designed for high capacitance density in a low-profile package, these capacitors offer extraordinary long-life and reliability suitable for ruggedized, commercial, and -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 -grade construction, high vibration resistance (up to 20g with HV option), and excellent capacitance retention at -55C.
