AMH461
Hybrid - High Reliability
EMI Filter
DESCRIPTION
FEATURES
The AMH Series EMI filter has been designed to provide n Up to 2.0 Ampere Output Current
full compliance with the input line reflected ripple
current requirement specified by CE03 of MIL-STD-
n
Attenuation > 60dB at 500KHz
461C over the extended military temperature range n Low Profile Seam Welded Package
while operating in conjunction with the corresponding
AHF series of DC/DC converters. These filters are
n
Ceramic Insulated Copper Core Pins
offered as part of a family of high reliability conversion n Operation Over Full Military Temp Range
products providing single, dual and triple output voltages
n
No Derating for –55ºC to +125º C
while operating from nominal +28 volt input line. Other
converters operating with a similar switching frequency
will also benefit from 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 Advanced Analog / M-3's rugged
ceramic lead-to-package seal assuring long term
hermetic seal integrity in harsh environments.

Designed to meet the 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
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
requirement, but does not include element evaluation.
The ES grade is processed and screened to a lower
level 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.
