MCOTS-F-28-T-HT
Current: 30A
Technical Specification
BASIC OPERATION AND FEATURES
The MCOTS-F-28-T is a multi-stage differential-mode and
common-mode 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 multilayer 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 MCOTS-F-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 MCOTS-F-28-T
EMI filter is designed to pass all the relevant MIL-STD-461D/E
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 MCOTS-F-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
MCOTS-C-28 DC/DC converter. The others require the transient
suppression circuitry of the MCOTS-F-28-T EMI filter to protect
the converter from an over-voltage condition. If MCOTS-C-28E
or MCOTS-C-28VE converters are used, voltage surges as high
as 80V can be tolerated without the need for this transient
suppression circuitry.
The MCOTS-F-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.
REVERSE POLARITY PROTECTION: The MCOTS-F-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 mΩ 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
MCOTS converters.
Product # MCOTS-F-28-T-HT
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.
ON/OFF: The MCOTS-F-28-T filter has enable pass-through
circuitry that bridges an enable signal across the filter’s
common-mode impedance. The ON/OFF INPUT pin (pin B) is
referenced with respect to the filter’s INPUT RETURN (pins 3 and
4). The ON/OFF OUTPUT pin (pin 8) is referenced with respect
to the filter’s OUTPUT RETURN (pin 5). The INPUT RETURN and
OUTPUT RETURN may have a different voltage due to commonmode noise and transients.
NOTE: During the time that the MCOTS-F-28-T filter is in its
­Soft-­Start mode the ON/OFF 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, ON/OFF OUTPUT will follow ON/OFF INPUT.
Figure A shows the equivalent circuit looking into ON/OFF
INPUT. The ON/OFF INPUT pin must be pulled low to turn an
MCOTS converter off. It may be left open-circuit to turn the
converter on.

when power is applied to the filter and ON/OFF INPUT is low. Otherwise, the MOSFET is off. Standard MCOTS converters
are enabled when their ON/OFF pin is held low. To interface
the enable output of the MCOTS-F-28-T filter with MCOTS
converters, add a N-type MOSFET as shown in the typical
connection diagram. For improved noise tolerance, a seperate
MOSFET can be used for each MCOTS converter, with their gates
isolated from each other with sense resistors.

If the enable pass-through circuit is not being used, the

SOFT-START: The MCOTS-F-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.
Once the input voltage exceeds the turn-on threshold value,
the Soft-Start circuitry controls the filter’s output current to be
approximately 1.8A. 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
Soft-Start 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.
OUTPUT POWER LIMIT: The MCOTS-F-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 ~675W 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.
STANDBY: The MCOTS-F-28-T filter has standby circuitry that
minimizes the power drawn from the filter’s input power source
when the standby feature is activated.
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 D shows the equivalent circuit looking into the STANDBY
pin (pin 6).
This pin is referenced with respect to the filter’s OUTPUT
RETURN pin (pin 5). 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.
Since, during Soft-Start, the filter will deliver only 1.8A 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 ON/OFF
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 Soft-Start mode is completed, ON/OFF OUTPUT
will follow ON/OFF INPUT.

MCOTS-F-28-T-HT
Current: 30A
Technical Specification
Application Note: A typical application would place the MCOTS
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 MCOTS-F-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 commonmode rejection performance.
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.
Figure E: Input over voltage shutdown envelope.
During this shutdown, power flow to the load is interrupted and
the filter’s ON/OFF 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.

Met by an MCOTS Filter having the Transient Suppression
and Reverse Polarity Protection Features
* 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.
** MCOTS-F-28-T filter only: Performance Criteria C. Filter will shut down and then automatically restart when the voltage returns to
normal limits.
§ 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 MCOTS-F-28-T but not the MCOTS-F-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 <1µs
