ADVANCED ANALOG
EMI FILTER
HYBRID / HIGH RELIABILITY
Description
The AME Series of EMI filters have been designed to
provide full compliance with the input line reflected
ripple current requirement specified by CE03 of MIL-
STD-461C over the full military temperature range while
operating in conjunction with the corresponding AFL
series of DC/DC converters.These filters are offered as
part of a complete family of conversion products pro-
viding single and dual output voltages while operating
from nominal +28, +50 or +270 input line voltage. Other
converters operating with a similar switching frequency
will also benefit by use of this device.
AME
Features
n Up to 7.0 Ampere Output Current
n Attenuation > 35dB @ 200 KHz
n Low Profile (0.38”) Seam Welded Package
n Ceramic Feedthru Copper-Core Pins
n Operation Over Full Military Temp. Range
n Standard Military Drawings Available
These EMI filters are hermetically packaged in two en-
closure variations, utilizing copper-core pins to mini-
mize resistive DC losses. Three lead styles are avail-
able, each fabricated with Advanced Analog’s rugged
ceramic lead-to-package seal assuring long term her-
metic seal integrity in harsh environments.
Both grades are tested to meet the complete
group “A” test specification over the full military
temperature range with no derating. Two grades
with more limited screening are also available
for use in less demanding applications. Varia-
tions in electrical, mechanical and screen re-
quirements can be accommodated. Contact Ad-
vanced Analog for special requirements.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are available in four screen-
ing grades to satisfy a wide range of applications. The
CH grade is fully compliant to the requirements of MIL-
PRF-38534 for class H. The HB grade is fully processed
and screened to the class H requirement, but does not
include element evaluation to the class H requirement.

Circuit Operation and Application Information
The AME series of filters employ three stages of fil-
tering in a low pass configuration designed to at-
tenuate the higher frequency components of ripple
currents generated by high frequency switching DC/
DC converters. The Block Diagram describes the
general arrangement of the principal elements which
have been connected to provide both differential and
normal mode buffering between the input and out-
put terminals.
When a single AME filter is used in conjunction with
multiple DC/DC converters, the use will be limited
to the maximum output current capability specified
in the AME electrical table.1 A typical connection
utilizing one filter to drive two converters is illus-
trated on page1.
Although expressly designed to complement the AFL
series of DC/DC converters, the AME50461 filters
can be successfully operated in conjunction with
other converters in the Advanced Analog line in-
cluding the ASA, AHF, AHV and ATR series.
Employing only passive elements, AME filter opera-
tion is initiated simply by insertion into the input power
path between one or more DC/DC converters and
their input DC voltage bus. In this connection, out-
put pins of the filter will be connected to input pins of
the converters.

To calculate the input current (i ) requirement of any one converter, first determine the maximum output power by
in
multiplying output voltage by maximum load current, divide this power by the efficiency to obtain input power and then divide
input power by input voltage to obtain the input current (i ). Note that to obtain worst case input current, you must use
in
maximum load current, minimum efficiency and minimum line voltage in this calculation.
