Product Overview
The MLPS/MLPSR 105 C Flatpack series by Cornell Dubilier are ultra-long life, very low profile aluminum electrolytic capacitors designed for high capacitance density in a compact package. Optimized for 105 C applications, these capacitors feature laser-welded seals and rugged construction, ensuring extraordinary long-life and reliability. They are ideal for ruggedized, commercial, and military-grade power supplies. The series has been fully tested to 10,000 hours at rated voltage and ripple current at 105 C, offering high vibration resistance (up to 20g with HV option) and excellent capacitance retention at -55 C. High Reliability burn-in is available.
