APPLICATIONS
Case material:non-conductive plastic(UL 91V-0 rated)
Weight: 2.0g (0.07oz)
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.

Specifcations can be changed any time without notice.
No parallel connection or plug and play.
Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
