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 compact applications. These military-grade capacitors offer exceptional long-life and reliability, suitable for ruggedized, commercial, and military-grade power supplies. They feature laser-welded seals to prevent dry-out and have been tested to 10,000 hours at rated voltage and ripple current at 105C. The series is optimized for 105C operation and exhibits high vibration resistance (up to 20g with HV option). Available in lead-free versions, these capacitors provide excellent capacitance retention at low temperatures.
