EMI FILTER
HYBRID / HIGH RELIABILITY
PD-94587
AMH461 SERIES
Description
The AMH 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 full military temperature range while operating in
conjunction with the corresponding AHF 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 AHF package
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 derating 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 CH grade
intended for flight use is fully compliant to the
requirements of MIL-PRF-38534 for class H. The HB
grade is processed and screened to the class H

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
requirements, but does not include element
evaluation. The ES grade is processed and
screened to a lower grade requirement. Class
CH grade and class HB grade are tested to meet
the complete group “A” test specification over
the full military temperature range with no
derating. Variations in electrical, mechanical and
screen requirements can be accommodated.

Notes to Specifications
1. Operation above maximum ratings may cause permanent damage to the device. Operation at maximum ratings may degrade
performance and affect reliability.
2. Device can tolerate ± 100 Volt transient whose duration is 100 ms when RS 0.5 .
3. Derate Output Current linearly from 100% at 125°C to 0 at 135°C.
4. DC resistance is the total resistance of the device and includes the sum of the input to output resistance and the return in to return
out resistance paths.
