Cornell Dubilier Aluminum Electrolytic MLP331M400EB0E

The MLP331M400EB0E is an aluminum electrolytic capacitor in the MLP Flatpack series, designed for voltage holdup and filtering in high-reliability applications. It has a case size EB with a length of 3.0 inches and weighs 66 g typical. The part operates at 400 Vdc with a capacitance of 330 µF and a tolerance of ±20%. It features a nearly hermetic welded seal for 50-year life at +45°C, withstands up to 80,000 feet altitude, and supports up to 85°C case temperature. Ripple current capability is rated at 2.1 A at 120 Hz and 2.5 A at 20 kHz. Thermal resistance with a heatsink is 1.3 °C/W. The capacitor has an ESL of less than 30 nH measured at 1 MHz and uses 18 AWG copper wire terminals with tin-lead electroplate. It meets MIL-STD-202 and IEC 60068-2-6 vibration standards and operates from -55°C to +85°C at voltages up to 450 Vdc.
