EMI FILTER
HYBRID-HIGH RELIABILITY
ARF
ARF461 SERIES
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
extended 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
packages as a convenience in system installation and is
fabricated with IR HiRel rugged ceramic lead-to-package
seal assuring long term hermetic seal integrity in harsh
environments.
Designed to meet the derating requirements of MIL-STD-
975 and manufactured in a facility fully qualified to MIL-
PRF-38534, these are available in two screening grades.
The flight grade is designed, screened and processed for
space as specified in MIL-PRF-38534 for Class K.
The EM grade is processed and screened for
lower grade requirement. Both grades are tested to meet
the complete group “A” test specification over the full mili-
tary temperature range with no derating. Variations in electrical,
mechanical and screening requirements can be accommodated.
