Product Overview

The MLPS/MLPSR series from Cornell Dubilier are 105C Flatpack Ultra Long Life Aluminum Electrolytic Capacitors designed for high capacitance density in a very low-profile package. Featuring laser-welded seals and rugged construction, these capacitors offer extraordinary long-life and reliability, making them ideal for ruggedized, commercial, and military-grade power supplies. They have been fully tested to 10,000 hours at rated voltage and ripple current at 105C, providing high vibration resistance (up to 20g with HV option) and excellent capacitance retention at -55C. Available in lead-free versions, these capacitors are optimized for demanding 105C applications.
