Features

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. Contact Advanced Analog for special require- ments.

Operation above maximum ratings may cause permanent damage to the device. Operation at maximum ratings may degrade performance and affect reliability. 2. Device can tolerate ± 100 Volt transient whose duration is ≤ 100 ms when RS ≥ 0.5 Ω . 3. Derate Output Current linearly from 100% at 125°C to 0 at 135°C. 4. DC resistance is the total resistance of the device and includes the sum of the input to output resistance and the return in to return out resistance paths.
