2 / 18 page

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.
