C 02/05/15 Page 4 MQHE-270-P Current: 1.0A Technical Specification BASIC OPERATION AND FEATURES The MQHE-270-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 50Ω to chassis ground on each input line. The MQHE-270-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. Additional Damping Requirements: The MQHE-270-P will require an additional external damping network for some MQFL-270 converters. Consult the input impedance figure on the converter’s datasheet and the filter’s bulk capacitance and damping resistance in the specification table. With these values, the additional damping network can be calculated using the Input System Instability application note. 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 external transient suppression circuitry). The Section 22 Compliance Matrix Table on Page 6 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 MQHE-270-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. When used with SynQor’s DC/DC converters, the MQHE-270-P EMI filter is designed to pass all of the relevant MIL-STD-461C/D/ E/F requirements to their most stringent limits. 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.

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.
