PD-95856C
EMI FILTER
HYBRID - HIGH RELIABILITY
AFH461 SERIES
Description
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.
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.
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.

Features
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 San Jose for special
requirements.
