ARF

Typical Connection Diagram

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

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.

ments.
