Product Highlights
The M-FIAM7 is a DC front-end module that
provides EMI filtering and transient protection.
The M-FIAM7 enables designers using Vicor’s
28V DC-DC VI Chip modules to meet conducted
emission/conducted susceptibility per
MIL-STD-461E; and input transients per
MIL-STD-1275A/B/D, MIL-STD-704A-F and DO-
160E. The M-FIAM7 accepts an input voltage of
14 – 50VDC and delivers output current
up to 10A.
M-FIAM7 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 onboard
or inboard for height critical applications.
Compatible Products
•28V Input DC-DC VI Chip® modules
Note: This product is not compatible with Maxi,
Mini, Micro DC-DC converters.
[1] EMI performance is subject to a wide variety of
external influences such as PCB construction, circuit
layout etc. As such, external components in addition
to those listed herein may be required in specific
instances to gain full compliance to the standards
specified.
