Product Highlights

The M-FIAM5 is a DC front-end module
that provides EMI filtering and transient
protection required in military applications.
The M-FIAM5 enables designers using
Vicor 2nd Generation 24V DC-DC converters
to meet conducted emission/conducted
susceptibility per MIL-STD-461E; and
input transients per MIL-STD-704E1. The
M-FIAM5 accepts an input voltage of
18-36Vdc and delivers output current
up to 20 Amps.

M-FIAM5 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.
