Product Details

The Mil-COTS series of EMI filters brings SynQor’s field proven technology and manufacturing expertise to the military and aerospace industry. SynQor’s innovative 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. This filter, when combined with Mil-COTS DC-DC converters, is designed to comply with MIL-STD-704, MIL-STD-1275, RTCA/DO-160, DEF-STAN 61-5 and MIL-STD-461 for a 28Vin system.
