PD-94588A
ARF461 SERIES
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-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 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 International Rectifier’srugged
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
screenedto 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.
