The MilQor^® series of high-reliability EMI filters brings SynQor’s
field proven technology and manufacturing expertise to the
Military/Aerospace industry. SynQor’s innovative QorSeal^TM pack-
aging approach ensures survivability in the most hostile environ-
ments. Compatible with the industry standard format, these
filters have high differential-mode and common-mode attenua-
tion, low DC resistance, and a stabilizing bulk capacitor resistor.
They follow conservative component derating guidelines and
they are designed and manufactured to comply with a wide
range of military standards.
