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

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.

AME

Features

n Up to 1.5 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

enclosure variations, utilizing copper-core pins to

minimize resistive DC losses. Three lead styles are

available, each fabricated with Advanced Analog’s

rugged ceramic lead-to-package seal assuring long

term hermetic 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. Variations

in electrical, mechanical and screen requirements

can be accommodated. Contact IR Sant Clara

for special requirements.

Manufactured in a facility fully qualified to MIL-PRF-

38534, 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 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

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

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 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 output

terminals.

capability specified in the AME electrical table.¹

typical connection utilizing one filter to drive two

converters is illustrated on page 1.

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 inputvoltage 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.
