The MLP491M250EA0C is an aluminum electrolytic capacitor in the MLP series, designed for voltage holdup and filtering in high-reliability applications. It has a 2.0-inch case length (EA), rated for 250 Vdc with a capacitance of 490 µF and ±20% tolerance. Maximum ESR is 285 mΩ at 120 Hz, with a ripple current of 2.4 A at 85 °C. The unit features a nearly hermetic welded seal for 50-year life at +45 °C and withstands up to 80,000 feet altitude. It uses 18 AWG copper wire terminals with mounting tabs and weighs 42 g. Endurance is rated for 2000 hours at +85 °C under full load. Thermal resistance is 1.9 °C/W when heatsinked. Vibration compliance meets MIL-STD-202 Method 204 and IEC 60068-2-6 with 10g testing. ESL is under 30 nH at 1 MHz. Operating temperature is -40 °C to +85 °C for voltages ≥300 Vdc.
