G11 High Temperature Tubes
G11 Glass Reinforced Epoxy is similar to G10/FR4, with the addition of a higher operating
temperature and some improved mechanical strength at elevated temperatures. G11 is superior for electrical insulation
in both dry and moist environments, because of its higher flame resistance and also
because water absorption is practically zero. The main difference between NEMA Grades
G11 and FR5 is that FR5 is a fire retardant grade of G11. Therefore, FR5 can be
safely substituted when G11 is called for, while G11 can never be substituted
where FR5 is called for.
NEMA G-11 certs to MIL-I-24768/3 GEB, IEC 60893-3 Type
2 EP GC 203 • FR5 certifies to MIL-I-24768/28 GEB-F.
