Product Details

The MilQor® series of high-reliability DC-DC converters brings SynQor’s field proven high-efficiency synchronous rectifier technology to the Military/Aerospace industry. SynQor’s innovative QorSeal® packaging approach ensures survivability in the most hostile environments. Compatible with the industry standard format, these converters operate at a fixed frequency, have no opto-isolators, and follow conservative component derating guidelines. They are designed and manufactured to comply with a wide range of military standards.
