MQHE-28E-P
Current: 10A
Technical Specification
BASIC OPERATION AND FEATURES
The MQHE 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 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.
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 MQHE
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 MQHL-28 DC/DC converter.

V in(+)
When used with SynQor’s DC/DC converters, the MQHE 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 lists these requirements and describes
the setup used to pass them. Figures 3 - 6 show results from
selected conductive and radiated emissions tests.
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. 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 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 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 common-mode
chokes to saturate and thus cause degraded common-mode
rejection performance.

* 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.

† 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.

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
