* Input voltage can

’t exceed this value, or will cause the permanent damage.

FEATURES

● Wide (2:1) Input Range

● Short Circuit Protection(automatic recovery)

● 1500VDC Isolation

● Operating Temperature: -40°C ~ +85°C

● No heat sink required

● No external component required

● Internal SMD required

● Five sided metal shielding

● MTBF>1000Khours

● RoHS Compliance

APPLICATIONS

The WRA_YMD-3W & WRB_YMD-3W Series are

specially designed for applications where a wide

range input voltage 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 dem anded.
