product # MQME-270-r phone 1-888-567-9596 www.synqor.com doc.# 005-0006166 rev. e 05/31/2016 page 6 MQME-270-r current: 2a technical specification basic operation and features the MQME-270-r is a multi-stage differential-mode and common- mode passive emi flter designed to interface a power source with one or more synqor dc/dc converters (or other loads that create emi). each stage of this flter 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 flter when the source impedance is 50w to chassis ground on each input line. the MQME-270-r emi flter includes a large bulk capacitor (also x7r) with a series damping resistor to correct for the unstabilizing effect of a converters 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 flters output impedance when the flter input is connected to a stiff voltage source. when used with synqors dc/dc converters, the MQME-270-r emi flter 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 lists these requirements and describes the setup used to pass them. figures 3 - 6 show results from selected conductive and radiated emissions tests. the flter is also designed to pass the waveform types and applications specifed in rtca/do-160e/f/g section 22 (lightning induced transient susceptibility) to level 4 (some waveforms / applications require external transient suppression circuitry). the section 22 compliance matrix table lists these waveforms and applications and describes the setup used to pass them. a typical application would place the mqme flter close to the input of the dc/dc converter, with the cases of the flter 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-270-r flters in parallel. connecting flters in this manner may result in slightly unequal currents to fow in the positive and return paths of each flter. these unequal currents may cause the internal common-mode chokes to saturate and thus cause degraded common-mode rejection performance. reverse polarity protection: the MQME-270-r emi flter has a series-connected diode. this diode blocks reverse current fow if the flter's input voltage is mistakenly connected with the wrong polarity. the anti-parallel diode, working with the reverse polarity diode, ensures that the flter's output voltage goes only slightly negative during this time, and therefore satisfying the minimum input voltage specifcations of synqor's mqfl converters. the reverse polarity diode also preforms a useful function during negative polarity spikes and surges, and during brief power interrupts. since it stops current from fowing negatively through the emi flter back toward the source, thediode allows the total bulk capacitor (located both within and external to the flter) to better hold up the output voltage during these transients.
