The MLP491M250EA1A is a flatpack aluminum electrolytic capacitor designed for voltage holdup and filtering in high-reliability applications such as military and telecom systems. It features a 2.0-inch case length, a rated voltage of 250 Vdc, and a capacitance of 490 µF with a tolerance of ±20%. The capacitor supports a maximum ripple current of 2.4 A at 20 kHz and 85 °C, with an ESR of 285 mΩ at 120 Hz. It operates from -40 °C to +85 °C, maintains a 50-year life at +45 °C, and has a 30 nH equivalent series inductance measured at 1 MHz. The case is aluminum with polyester insulation and mounting tabs, weighs 42 g typical, and is rated for vibration up to 10g per MIL-STD-202 Method 204. It withstands altitudes exceeding 80,000 feet and endsurance-tested for 2000 hours at full load at +85 °C.
