Minmax's MSAU400 2W DC/DC's
are in "gull-wing" SMT package, weigh
a mere 2.2 grams and meet 245°C/10sec in solder-reflow
for lead free process.
The series consists of 13 models
with input voltages of 5V,12V and 24VDC which
offers standard output voltages of 5V, 12V, ±5V, ±12V and ±15VDC for the choice. Their impressive guaranteed
efficiencies enable all models to deliver their
fully rated output power from -40°C to +85°C without
heat sinking or forced-air cooling.
The MSAU400 series is an excellent
selection for a variety of applications including
data communication equipments, distributed power
systems, telecommunication equipments and industrial
robot systems.
The MSAU400 units are available
in tape and reel package.

Notes
:
1.
Specifications
typical at Ta=+25°C, resistive load, nominal
input voltage, rated output current unless
otherwise noted.
2.
These power converters require
a minimum output load to maintain specified
regulation.
3.
Operation under no-load conditions
will not damage these modules; however, they
may not meet all specifications listed.
4.
All DC/DC converters should
be externally fused at the front end for protection.
5.
Other input and output voltage
may be available, please contact factory.
6.
All specifications subject
to change without notice.
