AMH461 SERIES

EMI FILTER

HYBRID / HIGH RELIABILITY

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.

AMH

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

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.

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.

Contact IR Santa Clara for special requirements.

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

Notes to Specifications

Operation above maximum ratings may cause permanent damage to the device. Operation at maximum ratings may degrade

performance and affect reliability.

Device can tolerate ± 100 Volt transient whose duration is ≤ 100 ms when R_S≥ 0.5 Ω.

Derate Output Current linearly from 100% at 125°C to 0 at 135°C.

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.
