AME270461 SERIES
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 MILSTD-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
providing single and dual output voltages while
operating from nominal +270 input line voltage. Other
converters operating with a similar switching frequency
will also benefit by use of this device.

These EMI filters are hermetically packaged in two
enclosure variations, utilizing copper-core pins to
minimize resistive DC losses. Three lead styles are
available, each fabricated with International Rectifier’s
rugged ceramic lead-to-package seal assuring long
term hermetic seal integrity in harsh environments.
Up to 1.5 Ampere Output Current
Attenuation > 35dB @ 200 KHz
Low Profile (0.38”) Seam Welded Package
Ceramic Feedthru Copper-Core Pins
Operation Over Full Military Temp. Range
Standard Military Drawings Available
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. Variations
in electrical, mechanical and screen requirements
can be accommodated. Contact IR San Jose for
special requirements.
Manufactured in a facility fully qualified to MIL-PRF38534, these converters are available in four screening
grades to satisfy a wide range of applications. The CH
grade is fully compliant to the requirements of MILPRF-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
filtering in a low pass configuration designed to
attenuate the higher frequency components of ripple
currents generated by high frequency switching DCDC 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 output
terminals.
Employing only passive elements, AME filter
operation 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,
output pins of the filter will be connected to input
pins of the converters. 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 illustrated on page 1.

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