MQME-28-T
Current: 20A
Technical Specification
BASIC OPERATION AND FEATURES
The MQME-28-T 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-T 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-28-T
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-28-T 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-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.
The MQME-28-T 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-28-T 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-28-T
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-28-T 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-28-T filter is in its Soft-Start
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-28-T 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-28-T 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-28-T 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.

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 converters and filters are offered in three variations of environmental stress screening options. All MilQor 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.
