APPLICATIONS
The NTA-X series are miniature,1W 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.
