Cornell Dubilier Aluminum Electrolytic MLP331M400EB1E

The MLP331M400EB1E is an aluminum electrolytic capacitor in the MLP 85 °C Flatpack series, designed for voltage holdup and filtering in high-reliability applications. It has a 3.0-inch case length (EB case code), a rated voltage of 400 Vdc, and a capacitance of 330 µF with ±20% tolerance. The part features a nearly hermetic welded seal for 50-year life at +45 °C, with a maximum operating temperature of +85 °C. It has a maximum ESR of 530 mΩ at 120 Hz and a rated ripple current of 2.1 A at +85 °C. The case is aluminum, with 18 AWG copper wire terminals, and the part meets MIL-STD-202 and IEC 60068-2-6 vibration standards. Thermal resistance from case to ambient is 1.3 °C/W when both large sides are equipped with polyester insulation. The ESL is less than 30 nH measured at 1 MHz, and the capacitor withstands more than 80,000 feet altitude.
