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^® packaging approach ensures
survivability in the most hostile environments. Compatible
with the industry standard format, these filters have high
differential-mode and common-mode attenuation, 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.
Design Process
MQME series filters are:
• Designed for reliability per NAVSO-P3641-A guidelines
