MQME-28-P Current: 20 A Technical Specification
BASIC OPERATION AND FEATURES
The MQME-28-P is a multi-stage differential-mode and commonmode passive EMI filter designed to interface a power source with one or more SynQor DC/DC converters (or other loads that create EMI). 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 50W to chassis ground on each input line. The MQME-28-P EMI filter includes a large bulk capacitor (also X7R) with a series damping resistor to correct for the unstabilizing effect of a converter's negative input resistance. A white paper discussing this negative input resistance and the need for corrective damping can be found on the SynQor website (see Input System Instability application note). Figure 2 shows the magnitude of the 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-28-P EMI filter 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. The others require the transient suppression circuitry of an MQME-28-T EMI filter to protect the converter from an over-voltage condition. If MQFL-28E or MQFL-28VE converters are used, voltage surges as high as 80V can be tolerated without the need for this transient suppression circuitry. When used with SynQor's DC/DC converters, the MQME-28-P EMI filter is designed to pass all of the relevant MIL-STD461C/D/E requirements to their most stringent limits. The MILSTD-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 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 MQME 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-28-P filters in parallel. Connecting filters in this manner may result in slightly unequal currents to flow in the positive and return paths of each filter. These unequal currents may cause the internal commonmode chokes to saturate and thus cause degraded common-mode rejection performance.

* Requirement is deemed to have been met as long as transient deviations in the converter's output voltage remain within 10% of its initial value. For these waveforms at Level 3 and above, an external transient suppressor of sufficient energy rating must placed across the filter's input pins to keep the differential transient input voltage below +200V/-50V. 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.

For the DEF STAN 61-5 specification: 1) Negative surges require reverse voltage protection circuitry to protect the converter (but not the filter) from a negative input. This circuitry is included in the MQME-28-T and MQME-28-HT filters but not the MQME-28-P filter. 2) The negative surges may cause the converter to shut down unless additional holdup capacitance is included. 3) Maximum spike voltages are assumed to last <1s.

MilQor converters and filters are offered in four variations of construction technique and environmental stress screening options. The three highest grades, C, ES, and HB, all use SynQor's proprietary QorSealTM Hi-Rel assembly process that includes a Parylene-C coating of the circuit, a high performance thermal compound filler, and a nickel barrier gold plated aluminum case. The B-grade version uses a ruggedized assembly process that includes a medium performance thermal compound filler and a black anodized aluminum case. Each successively higher grade has more stringent mechanical and electrical testing, as well as a longer burn-in cycle. The ESand HB-Grades are also constructed of components that have been procured through an element evaluation process that pre-qualifies each new batch of devices.
Note: Since the surface of the black anodized case is not guaranteed to be electrically conductive, a star washer or similar device should be used to cut through the surface oxide if electrical connection to the case is desired.
