SELECTION GUIDE

GUIDE

The A-XT-1W 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.
