The MLP491M250EA1C is a 250 Vdc, 490 µF aluminum electrolytic capacitor in the MLP Flatpack series, designed for voltage holdup and filtering in high-reliability applications. It features a 2.0-inch case length, weighs 42 g typical, and has a 18 AWG copper wire terminal with tin-lead electroplate. The capacitor operates from -40°C to +85°C at 250 Vdc, with a 50-year life at +45°C, a maximum ESR of 285 mΩ at 120 Hz, and a rated ripple current of 2.4 A at 85°C. Its thin profile and flat surfaces enable heatsinking to double ripple current capability. The case is aluminum, and the construction includes a nearly hermetic welded seal. It meets vibration testing per MIL-STD-202 and IEC 60068-2-6 with 10g amplitude. The part uses polyester insulation, as indicated by the '1' in the case code, and is not bare can construction.
