AF28461
AF28461 is EMI FILTER manufactured by Micross.
Description
The AF28461 Series EMI filter is designed to provide full pliance 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 50V input line. Other converters operating with a similar switching frequency could also benefit by use of this device.
The AF28461 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 Hi Rel’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 MILPRF-38534, and is available in two screening grades. The flight grade is designed with the requirements of MIL-PRF38534 for class K.
