Product Highlights
The M-FIAM5B is a DC front-end module that
provides EMI filtering and transient protection.
The M-FIAM5B enables designers using Vicor
Maxi, Mini, Micro Series 24V DC-DC converters
to meet conducted emission / conducted
susceptibility per MIL-STD-461E; and input
transients per MIL-STD-704E/F. The M-FIAM5B
accepts an input voltage of 14 – 36VDC and
delivers output current up to 20A.
M-FIAM5B is housed in an industry-standard
“half-brick” module measuring
2.28x2.2x0.5in and depending upon model
selected, may be mounted onboard or inboard
for height-critical applications.
