AFM704A SERIES
ADVANCED ANALOG
EMI FILTER / PROTECTION HYBRID
Description
The AFM704A is a combined EMI filter and protection
module intended to be used with Advanced Analog
AHE, ATO, ATR, ATW, AHF, ASA, and AHV DC/DC converters to allow full compliance with the surge requirements of MIL-STD-704.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-PRF-38534) devices. Standard Military Drawings
(SMDs) available.
