PD - 94598A AFM704A SERIES EMI FILTER / PROTECTION HYBRID Description The AFM704A is a combined EMI filter and protection module intended to be used with AHE, ATO, ATR, ATW, AHF, ASA, and AHV DC/DC converters to allow full compliance with the surge requirements of MIL-STD704A.This device will reduce reflected ripple current to levels below the CEO3 limits and protect against voltage spikes required by CS06 testing as specified by MIL-STD-461. Four levels of military screening are available, including fully compliant (per MIL-PRF38534) devices. Standard Military Drawings (SMDs) available.
