EMI FILTER

HYBRID - HIGH RELIABILITY

Description

These EMI filters are hermetically packaged in a seam

welded enclosure utilizing axially oriented copper-core

pins which minimize resistive DC losses. This package

has been configured to complement the AMA, AMF and

AMR packages as a convenience in system installation

and is fabricated with International Rectifier’s rugged

ceramic lead-to-package seal assuring long term

hermetic seal integrity in harsh environments.

Typical Connection Diagram

The AFH Series EMI filter has been designed to provide

full compliance with the input line reflected ripple current

requirement specified by CE03 of MIL-STD-461C over

the extended military temperature range while

operating in conjunction with the corresponding AMA,

AMF and AMR series of DC/DC converters. These

filters are offered as part of a family of high reliability

conversion products providing single, dual and triple

output voltages while operating from nominal +28 volt

input line. Other converters operating with a similar

switching frequency will also benefit by use of this

device.

Designed to meet the stringent requirements of military

and aerospace use, these devices are manufactured

in a facility fully qualified to MIL-PRF-38534, and are

available in two screening grades. The flight grade is

designed with the requirements of MIL-PRF-38534

for class K.

n Up to 2.0 A Output Current

n Attenuation > 60dB@500 KHz

n Low Profile Seam Welded Package

n Ceramic Insulated Copper Core Pins

n Operation Over Full Military Temp. Range

n No Derating for -55°C to +125°C

The EM grade is processed and screened to a

lower grade requirement. Flight grade are tested

to meet the complete group “A” test specifications

over the full military temperature range with no

derating. The design does not meet MIL-STD-

975 voltage derating requirements for some

ineternal components. Variations in electrical,

mechanical and screening requirements can be

accommodated. Contact IR Santa Clara for

special requirements.
