APPLICATIONS
*Input voltage can’t exceed this value,or will cause the permanent damage.
The WRA-YD-8W&WRB-YD-8W series is a family of high
performance 8W DC/DC converter modules featuring wide
2:1 input voltage ranges in a DIP-24 package with industry
standard footprint.
A very high efficiency allows an
operating temperature range of –40°C to +85°C. A built-in
EMI input filter complies with EN 55022, class A with
external components. Further standard features include
remote On/Off and short-circuit protection.
Typical applications for these converters are battery
operated equipment, instrumentation, communication and
industrial electronics, everywhere where isolated,tightly
regulated voltages are required and space is limited on the
PCB.

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.
