The ARH Series of DC/DC converters has been designed specifically for use in the hostile environments The high level of radiation tolerance inherent in the ARH design is the result of extensive research, thorough analysis and testing and of careful component specification. Designed to supplement the triple output configuration provided by the ART series, the ARH circuit topology is the follow-on to the successful ART design and incorporates many of the design features characterizing that product line. Capable of uniform high performance over long term exposures in radiation intense environments, this series expands the standard for distributed power systems demanding high performance and reliability in the harsh environments. The ARH converters are hermetically sealed in a rugged, low profile package utilizing copper core input and output pins to minimize resistive DC losses. Longterm hermeticity is assured through use of parallel seam welded lid attachment along with rugged ceramic pinto-package seal. Axial orientation of the leads facilitates preferred bulkhead mounting placing the converter on the principal heat-dissipating surface. Manufactured in a facility fully qualified to MIL-PRF38534, these converters are fabricated utilizing DSCC qualified processes.
