ADVANCED ANALOG
EMI FILTER
HYBRID / HIGH RELIABILITY
ARF461 SERIES
Description
The ARF Series EMI filter has been designed to pro-
vide 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 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 volt-
ages while operating from nominal +28 volt input line.
Other converters operating with a similar switching fre-
quency 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.
Designed to meet the the derating requirements of MIL-
STD-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 MIL-
PRF-38534. The HB grade is processed and screened
