APPLICATIONS
The QF(E)-XT series are miniature,0.25W DC/DC
converters with high isolation in a SMD package.With a
new package design these converters are qualified for the
higher temperatures requested by lead-free reflow solder
processes.With the small footprint,these converters are the
ideal solution for board level power distribution,mainly for
applications in the industrial and telecom field. For
automated SMD production lines the devices can be
supplied in standard tape and reel package.
