Product Highlights
The M-FIAM3 is a DC front-end module
that provides EMI filtering and transient
protection. The M-FIAM3 enables designers
using Vicor 2nd Generation 300V DC-DC
converters to meet conducted emission/
conducted susceptibility per MIL-STD-461E;
and input transients per MIL-STD-704E/F.
The M-FIAM3 accepts an input voltage of
180-375Vdc and delivers output current up
to 3 Amps.
M-FIAM3 is housed in an industry
standard "half brick" module measuring
2.28" x 2.2" x 0.5" and depending upon
model selected, may be mounted on-board
or in-board for height critical applications.
