Cornell Dubilier Aluminum Electrolytic MLP331M250EK1E

The MLP331M250EK1E is an aluminum electrolytic capacitor in the MLP FlatpackTM series, designed for voltage holdup and filtering in high-reliability applications. It features a 1.5-inch case length, a rated voltage of 250 Vdc, and a capacitance of 330 µF with a tolerance of ±20%. The capacitor has a maximum ESR of 426 mΩ at 120 Hz, a rated ripple current of 1.8 A at 85°C, and an ESL of less than 30 nH. It operates from -55°C to +85°C and has a 50-year life expectancy at +45°C. The case is made of aluminum, with lead-free terminals and polyester insulation. Weight is 30 g typical. Thermal performance allows a maximum case temperature rise of 88°C under load, and ripple current capability doubles when heatsinked. The capacitor meets MIL-STD-202 vibration standards and has a hermetically welded seal.
