PD-94586B EMI FILTER AFV461 SERIES De scription The AFV461 EMI filter will re duce the input line reflected ripple cu rrent of all DC/DC converter families t o levels below the CEO3 limits of MIL- STD-461. This filter is intended for ap plications requiring compatibility to M ILSTD-704A. These EMI filters are manuf actured in a facility certified to MIL- PRF-38534 and are available with milita ry screening. Four grades are offered w ith different screening options.
