Product Description
The MFM DCM™ Filter is a DC front-end module that provides
EMI filtering and transient protection. The MFM DCM Filter enables
designers using Vicor 28V nominal input voltage VIA™ or ChiP™
[a]
modules to meet conducted emission/conducted susceptibility
per MIL-STD-461E/F; and input transients per MIL-STD-704A/F,
MIL-STD-1275A/B/D/E and DO-160E. The MFM DCM Filter accepts
an input voltage of 16 – 50V
DC
(28V
nominal input
) and delivers
output power up to 350W.
