A white paper discussing this negative input resistance and the need for corrective damping can be found on the SynQor website (see Input System Instabilityapplicationnote).Figure2showsthemagnitudeofthe filter’s output impedance when the filter input is connected to a stiff voltage source. The input voltage surge and spike compliance matrix shown on Page 8 displays the worst case requirements listed in various 28V Military (Vehicle and Aircraft) and Civil Aircraft standards. The MQME-28E-P EMIfilter is designed to handle all of the short duration voltage spike requirements of these standards (with certain assumptions regarding DEF-STAN 61-5). Some of the long duration voltage surge requirements remain within the 50V maximum transient rating of a SynQor MQFL-28 DC/DC converter.Theothersrequirethetransientsuppressioncircuitryof an MQME-28-T EMIfilter to protect the converter from an overvoltage condition.

Product # MQME-28E-P Phone 1-888-567-9596 When used with SynQor’s DC/DC converters, the MQME-28E-P EMI filter is designed to pass all of the relevant MIL-STD-461C/ D/Erequirementstotheirmoststringentlimits.TheMIL-STD-461 ComplianceMatrixTableonPage7liststheserequirementsand describesthesetupusedtopassthem.Figures3-6showresults from selected conductive and radiated emissions tests. The filter is also designed to pass the waveform types and applications specified in RTCA/DO-160E Section 22 (Lightning Induced Transient Susceptibility) to Level 4 (some waveforms/ applications require the MQME-28-T filter and/or external transient suppression circuitry). The Section 22 Compliance Matrix Table on Page 9 lists these waveforms and applications and describes the setup used to pass them. A typical application would place the MilQor filter close to the input of the DC/DC converter, with the cases of the filter and the converter connected together through a ground plane. Both cases are electrically conductive, so connection to the cases can be made with the fasteners used to secure the device. Do not connect the outputs of multiple MQME-28E-P filters in parallel. Connecting filters in this manner may result in slightly unequalcurrentstoflowinthepositiveandreturnpathsofeach filter. These unequal currents may cause the internal commonmode chokes to saturate and thus cause degraded common-mode rejection performance. www.synqor.com Doc.# 005-0005135 Rev.
