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.¹A 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

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

maximum load current, minimum efficiency and minimum line voltage in this calculation.
