IRF ARF461

PD - 94588
ARF461 SERIES
ADVANCED ANALOG
EMI FILTER
HYBRID / HIGH RELIABILITY
Description
The ARF Series EMI filter has been designed to provide full compliance with the input line reflected ripple
current requirement specified by CE03 of MIL-STD461C over the full military temperature range while
operating in conjunction with the corresponding ART
and ARH 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 ART and ARH
package as a convenience in system installation and
is fabricated with Advanced Analog’s rugged ceramic
lead-to-package seal assuring long term hermetic seal
integrity in harsh environments.
Up to 3.0 Ampere Output Current
Attenuation > 40dB @ 100 KHz
Low Profile Seam Welded Package
Ceramic Feedthru Copper-Core Pins
Operation Over Full Military Temp. Range
No Derating for -55°C to +125°C Operation
to the class H requirement, but does not include
element evaluation. Both grades 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 Advanced Analog for special requirements.
Designed to meet the the derating requirements of MILSTD-975 and manufactured in a facility fully qualified
to MIL-PRF-38534, these converters are available in
two screening grades. The flight grade is designed,
screened and processed for space as specified in MILPRF-38534. The HB grade is processed and screened

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.
Device can tolerate ± 100 Volt transient whose duration is ≤ 100 ms when RS ≥ 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.
