MLP821M250EB1A

Type MLP 85 °C FlatpackTM, Ultra Long Life, Aluminum Electrolytic Very Low Profile The MLP’s high-energy storage and box-shape make it perfect for voltage holdup or filtering in military SEM-E modules, telecom circuit packs and computer cards. The MLP delivers up to 20 joules of energy storage in a 1/2” height with 50 year’s life at +45 ºC. You can readily heatsink it to double the ripple-current capability. The MLP is the square-peg component that fits the square-holes in electronic assemblies. Highlights - Low-profile replacement for snap-ins - Double the ripple capability with a heatsink - Nearly hermetic welded seal assures 50-year life - Withstands more than 80,000 feet altitude Specifications Temperature Range –55°C to +85°C ≤250 Vdc –40°C to +85°C ≥300 Vdc Rated Voltage Range 7.5 Vdc to 450 Vdc Capacitance Range 110 µF to 47,000 µF Capacitance Tolerance ±20% Leakage Current ≤ 0.002 CV µA, @ 25 °C and 5 min.

Amplitude The specimens shall be subjected to a simple harmonic motion having an amplitude of either 0.06-inch double amplitude (maximum total excursion) or peak level specified above (XXg peak), whichever is less. The tolerance on vibration amplitude shall be ±10 percent. Frequency Range The vibration frequency shall be varied logarithmically between the approximate limits of 10 to 2,000 Hz. Sweep Time and Duration The entire frequency range of 10 to 2,000 Hz and return to 10 Hz shall be traversed in 20 minutes. This cycle shall be performed 12 times in each of three mutually perpendicular directions (total of 36 times), so that the motion shall be applied for a total period of approximately 12 hours. Interruptions are permitted provided the requirements for rate of change and test duration are met.
