IRF AFM704AN/CH Emi filter / protection hybrid Datasheet

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.
