Products Highlights
The FM48 input filter module
enables designers to meet the
conducted emission limits of
EN55022 level B and FCC level B
when used with Vicor’s 48 Volt
2nd Generation of DC-DC
converters. FiltMods accept an
input voltage of 36 to 76 Vdc with
a transient withstand capability of
100Vdc for 100 msec. The FiltMods
are packaged in an industry
standard “quarter-brick” module
measuring 2.28" x 1.45" x 0.5"
and are available in either 8 or 12
Ampere capacity. Both versions
may be on-board mounted or
in-board mounted for height critical
applications. The FiltMods can be
teamed with Vicor’s IAM48 for
transient and surge protection.
