Product Highlights
The M-FIAM3 is a DC front-end module
that provides EMI filtering and transient
protection required in military applications.
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. 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.
