Features include small size, high efficiency, low weight and a high tolerance to total ionizing dose, single event effects and environmental stresses such as temperature extremes, mechanical shock, and vibration. All components are fully de-rated to meet the requirements of MIL-STD-975, MIL-STD-1547 and NASA EEE-INST-002. Extensive documentation including Radiation Susceptibility, Thermal Analysis, Stress Analysis and MTBF are available.<\/p>\n<p style=\"text-align: justify;\">The ARE Series converters incorporate a fixed frequency flyback topology with magnetic feedback and an internal EMI filter utilizing large multilayer ceramic capacitors processed per MIL-PRF-49470 for improved reliability. All models include an external inhibit port. They are encased in a hermetic 1.20&#8243; x 1.20&#8243; x 0.31\u201d AlSi package and weigh less than 15 grams. The package utilizes rugged ceramic feed-through copper core pins and is hermetically sealed using laser welding.<\/p>\n<p style=\"text-align: justify;\">Environmental screening includes temperature cycling, constant acceleration, fine and gross leak, and burn-in as specified by MIL-PRF-38534 for class K hybrids.<\/p>\n<p style=\"text-align: justify;\">Non-flight versions of the ARE Series converters are available for system development purposes.
