Description
The MR series are regulated DC-DC converters with upgraded MIL screened / qualified components and expanded operating temperature range. The 6-sided epoxy insulated shielded case is in a low profile package – 1.900″ x 1.000″ x 0.300″. Over 40 models are available in both single and dual isolated outputs. They can operate over the wide temperature range of -55°C to +85°C without derating, a heat sink or active cooling.
