MilQor converters and filters are offered in four variations of construction technique and environmental stress screening options. The
three highest grades, C, ES, and HB, all use SynQor’s proprietary QorSeal™ Hi-Rel assembly process that includes a Parylene-C coat-
ing of the circuit, a high performance thermal compound filler, and a nickel barrier gold plated aluminum case. The B-grade version
uses a ruggedized assembly process that includes a medium performance thermal compound filler and a black anodized aluminum
case^†. Each successively higher grade has more stringent mechanical and electrical testing, as well as a longer burn-in cycle. The ES-
and HB-Grades are also constructed of components that have been procured through an element evaluation process that pre-qualifies
each new batch of devices.
† Note: Since the surface of the black anodized case is not guaranteed to be electrically conductive, a star washer or similar device
should be used to cut through the surface oxide if electrical connection to the case is desired.
