components suitable for space applications. Requirements vary widely depending on many factors including the component type, materials, and other details specific to the flight program. Mini-Circuits has successfully screened hi-rel components for a range of space requirements, and this experience has enabled us to develop well- established qualification processes for these demanding applications. For more information about qualifying parts for space applications, please contact our applications team
