Each stage of this filter is well damped to avoid resonances and oscillations, and only X7R multi-layer ceramic capacitors are used. Figure 1 shows the typical differential and common-mode attenuation provided by this filter when the source impedance is 50Ω to chassis ground on each input line.

The MIL-STD-461 Compliance Matrix Table on Page 7 lists these requirements and describes the setup used to pass them. Figures 3 - 6 show results 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 The MQME-270-P EMI filter includes a large bulk capacitor (also Induced Transient Susceptibility) to Level 4 (some waveforms/ X7R) with a series damping resistor to correct for the unstabilizing applications require the MQME-270-T filter and/or external effect of a converter’s negative input resistance.

The Section 22 Compliance Matrix discussing this negative input resistance and the need for corrective Table on Page 9 lists these waveforms and applications and damping can be found on the SynQor website (see Input System describes the setup used to pass them.

Figure 2 shows the magnitude of the filter’s output impedance when the filter input is connected to a stiff A typical application would place the MQME filter close to the input of the DC/DC converter, with the cases of the filter and the voltage source. converter connected together through a ground plane.

The MQME-270-P EMI filter is designed to handle all of the short Do not connect the outputs of multiple MQME-270-P filters in duration voltage spike requirements of these standards (with certain parallel. Connecting filters in this manner may result in slightly assumptions regarding DEF-STAN 61-5). Some of the long duration unequal currents to flow in the positive and return paths of each voltage surge requirements remain within the 50V maximum filter. These unequal currents may cause the internal commontransient rating of a SynQor MQFL-270 DC/DC converter. The mode chokes to saturate and thus cause degraded common-mode others require the transient suppression circuitry of an MQME-270-T rejection performance. EMI filter to protect the converter from an over-voltage condition. If MQFL-270E or MQFL-270VE converters are used, voltage surges as high as 80V can be tolerated without the need for this transient suppression circuitry.

Negative polarity waveforms may cause power flow to the converter to be interrupted long enough to cause a graceful shutdown and restart of the converter. Also, the reverse voltage protection feature of the -T filter is required to protect the converter (but not the filter) from negative polarity waveform. ** For this waveform at a Level 4 and above, external transient suppressors of sufficient energy rating must be added between the filter’s input power pins and its case to keep the common-mode transient input voltage below +800V.
