MQME-28E-T6
Current: 20A
Technical Specification
BASIC OPERATION AND FEATURES
The MQME-28E-T6 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-28E-T6 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.
When used with SynQor’s DC/DC converters, the MQME-28E-T6
EMI filter is designed to pass all 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.
TRANSIENT SUPPRESSION: The input voltage surge and spike
compliance matrix displays the worst case requirements listed in
various 28V Military (Vehicle and Aircraft) and Civil Aircraft
standards. The MQME-28E-T6 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 the MQME-28E-T6 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.
The MQME-28E-T6 EMI 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.
The Section 22 Compliance Matrix Table lists these waveforms
and applications and describes the setup used to pass them.
REVERSE POLARITY PROTECTION: The MQME-28E-T6
EMI filter has a series-connected MOSFET that is controlled to
function as a diode, but with a very small forward voltage drop
(≤ 4 mW x Iout). This “Synchronous Rectifier” blocks reverse
current flow if the filter’s input voltage is mistakenly connected
with the wrong polarity. The anti-parallel diode, working with the
synchronous rectifier, ensures that the filter’s output voltage goes
only slightly negative during this time, and therefore satisfying
the minimum input voltage specifications of SynQor’s MQFL
converters.
Product # MQME-28E-T6
Phone 1-888-567-9596
The synchronous rectifier also performs a useful function during
negative polarity spikes and surges, and during brief power
interrupts. Since it stops current from flowing negatively through the
EMI filter back toward the source, the synchronous rectifier allows
the total bulk capacitor (located both within and external to the
filter) to better hold up the output voltage during these transients.
ENABLE: The MQME-28E-T6 filter has enable pass-through
circuitry that bridges an enable signal across the filter’s commonmode impedance. The ENABLE INPUT pin (pin 4) is referenced
with respect to the filter’s INPUT RETURN (pins 5 and 6). The
ENABLE OUTPUT pin (pin 9) is referenced with respect to the
filter’s OUTPUT RETURN (pin 7). The INPUT RETURN and
OUTPUT RETURN may have a different voltage due to commonmode noise and transients.
NOTE: During the time that the MQME-28E-T6 filter is in its SoftStart mode the ENABLE OUTPUT will be held at a logic low. This is
done so that all of the filter’s loads can be disabled by this signal
during the Soft-Start period. Once the Soft-Start is completed,
ENABLE OUTPUT will follow ENABLE INPUT.
Figure A shows the equivalent circuit looking into ENABLE INPUT.
The ENABLE INPUT pin must be pulled low to turn an MQFL
converter off. It may be left open-circuit to turn the converter on.

Figure B shows the equivalent circuit looking into ENABLE
OUTPUT. The n-channel MOSFET in this circuit turns on when
power is applied to the filter and ENABLE INPUT is low.
Otherwise, the MOSFET is off. ENABLE OUTPUT is capable of
driving the ENABLE INPUTs of up to 15 MQFL converters.
If the enable pass-through circuit is not being used, the
ENABLE INPUT pin may be left open or connected to the
INPUT RETURN pins. The ENABLE OUTPUT pin may be left open
or connected to the OUTPUT RETURN pins.
SOFT-START: The MQME-28E-T6 filter incorporates Soft-Start
circuitry to limit the amount of current drawn from the power
source by the charging of large bulk capacitors at the filter’s
output.

(OUTPUT RETURN)
Figure B: Equivalent circuit looking into the ENABLE OUTPUT pin
with respect to the OUTPUT RETURN pin.
Once the input voltage exceeds the turn-on threshold value,
the Soft-Start circuitry controls the filter’s output current to be
approximately 1.6A. This mode of operation continues until the
filter’s output voltage reaches the input voltage, at which time the
filter is able to deliver its rated output current. If after the SoftStart duration period the filter’s output has not risen to the input
voltage, then the filter will disconnect the output from the input,
wait for a time equal to the Soft-Start recycle period, and initiate
a new Soft-Start.
Since, during Soft-Start, the filter will deliver only 1.6A to its
output, it is important to limit the load current so that the total bulk
capacitance can be fully charged before the Soft-Start duration
period is over. To facilitate this, the filter’s ENABLE OUTPUT pin
is held low during the Soft-Start mode. This signal can therefore
be used to disable the filter’s loads during this time. Once the SoftStart mode is completed, ENABLE OUTPUT will follow ENABLE
INPUT.

Figure D shows the equivalent circuit looking into the STANDBY
pin (pin 8).
This pin is referenced with respect to the filter’s OUTPUT RETURN
pin (pin 7). It should be pulled low to have the filter operate in
its normal mode. If the pin is instead left open-circuit and pulled
high by its internal circuitry, the standby feature will be activated.
Application Note: 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-28E-T6 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.

Power Output (W)
Output Current (A)
OUTPUT POWER LIMIT: The MQME-28E-T6 filter has an
output power limit feature to protect against a short circuit at its
output pins. This limit is disabled whenever the output voltage is
rising so that it will not be encountered when charging output
capacitance. When the output power exceeds ~450W and its
output voltage is decreasing however, this feature will turn the
filter off and reinstitute a soft-start cycle in 500ms. Figure C shows
the output power limit threshold as a function of output voltage.
It does this in two ways. First, the output of the filter is disconnected
from the input so that there will be no power drawn by downstream
converters or other loads. Second, the active circuitry within the
filter is placed into a reduced power consumption mode. The
net result is a current draw of only about 2mA from a 28V input
power source.

Figure E: Input over voltage shutdown envelope.
INPUT OVER VOLTAGE SHUTDOWN: To protect itself from
damage due to sustained excessive power dissipation, the filter will
shut down if the input voltage versus time exceeds the envelope in
Figure E.
During this shutdown, power flow to the load is interrupted and
the filter’s ENABLE OUTPUT pin is pulled LOW. When the input
voltage returns to normal limits (and a Soft-Start Recycle Period has
elapsed), the filter automatically begins a Soft-Start cycle.
All of the surges listed in the VOLTAGE SURGE AND SPIKE
COMPLIANCE MATRIX on page 11 fall below the Figure E envelope.
Only the DEF STAN 61-5 (Part 6)/6 DIT08.B surge exceeds this
envelope. During a DIT08.B surge the filter will shutdown and
then automatically restart once the surge passes. This meets the
requirements of DEF STAN 61-5 (Part 6)/6 at Performance Criterion
C while the DIT08.B test requires only Performance Criterion D.

Performance Criteria C
* Surge/spike requirements/limits are deemed to have been met as long as transient deviations in the converter’s output voltage
remain within ±10% of its initial value.
§ These are defined as the maximum disturbances that equipment can inflict upon the power system, not as disturbances imposed
upon utilization equipment. To ensure compatablitily, however, these are within the designed stress envelope of the indicated filters
& converters.
† 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 but not the MQME-28-P and MQHE-28-P filters.
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 <1µs

Met by an MQME Filter having the Transient Suppression
and Reverse Polarity Protection Features
* 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.

MilQor® Hi-Rel converters and filters are offered in three variations of environmental stress screening options. All ES-Grade and HB-Grade MilQor
Hi-Rel converters use SynQor’s proprietary QorSeal® 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. Each successively higher grade has more stringent mechanical and
electrical testing, as well as a longer burn-in cycle. The ES- and HB-Grades are also constructed of components that have been procured through an
element evaluation process that pre-qualifies each new batch of devices.
