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.
