ESCRIPTIONS
The 100WFS 1 watt DC-DC converters are in “gull-wing” SMT
packages. They can withstand lead temperatures up to
+230
o
C and are compatible with contemporary pick-and-place
and solder-reflow processes.
The series is an excellent selection for a wide variety of
applications including data communication equipment,
distributed power systems, telecommunication equipment,
and industrial robot systems.
