DESCRIPTION
The WRA_YMD-5W& WRB_YMD-5W series are specially
designed for applications where a group of polar power
supplies are isolated from the input power supply in a
distributed power supply system on a circuit board.
These products apply to:
1) where the voltage of the input power supply is wide
range (voltage range ≤2:1);
2) where isolation is necessary between input and output
(isolation voltage ≤1500VDC);
3) where the regulation of the output voltage and the
output ripple noise are demanded.

When the environment temperature is higher than 71°C, the product output ower
71°
should be less then 60% of the rated power.
No parallel connection or plug and play.
Use dual output simultaneously, forbid opening output pin (0V) to use as single
output.
NC:No connection
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 data sheet, 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.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
