AF100461 SERIES
Description
AF100461 Series is part of the International Rectifier HiRel
family of products. The AF100461 Series EMI filter is
designed to provide full compliance with the input line
reflected ripple current requirement specified by MIL-STD-
461C and MIL-STD-461F over the extended temperature
range while operating in conjunction with the corresponding
ARA and ARE Series of DC-DC converters. The filter is
offered as part of a family of high reliability conversion
products that operate up to 110V input line. Other
converters operating with a similar switching frequency
could also benefit by use of this device.
The AF100461 filter is hermetically sealed in a seam
welded enclosure utilizing axially oriented surface-
mountable copper-core pins which minimize resistive
losses. The package is fabricated with IR HiRel’s rugged
ceramic lead-to-package seal assuring long term hermetic
seal integrity in harsh environments.
The filter is manufactured in a facility fully qualified to
MIL-PRF-38534, and is available in two screening grades.
The flight grade is designed with the requirements of
MIL-PRF-38534 for class K.
The EM grade are processed and screened to a lower
grade requirement. Flight grade are tested to meet
the complete group “A” test specifications over the
wide temperature range with no derating. The filter is
designed to meet the derating guidelines of
MIL-STD-1547 and EEE-INST-002.

Notes
1. One AF100461 filter is designed to accommodate up to two converters over rated voltage with rated load while not
exceeding maximum power limit.
2. To obtain specified EMI performance, it is recommended that conductor length between filter and converter to be kept
under 3 inches.
3. Meets derating under the following conditions: Nominal V

Notes to Specifications
1. Maximum ratings specified here relate to the Filter assembly. Any connected converter/device will have its own limits to
consider. 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 ± 150 Volt transient whose duration is 100ms when R

3. 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.
4. Derating guidelines do not apply for any input voltage transient conditions.
