ARF

Typical Connection Diagram

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.

Variations in electrical, mechanical and screen

requirements can be accommodated. Contact

IR Santa Clara for special requirements.
