DESCRIPTION

± 15 VDC
The WRA-YT-2W&WRB-YT-2W series is a family of high
performance 2W DC/DC converter modules featuring wide
2:1 input voltage ranges. The 28 models come in a low
profile SMD package which requires just 3 cm2 space on
the PCB.
A
high efficiency allows an operating
temperature range of –40°C to 71°C without derating. A
built-in EMI input filter complies with EN 55022, class A.
Typical applications for these converters are battery
operated equipment, instrumentation, communication and
industrial electronics, everywhere where isolated, tightly
regulated voltages are required.

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. Capacitor MAX load tested at input voltage range and full load.
4. All specifications measured at Ta=25℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
6. In this data sheet, all the test methods of indications are based on corporate standards.
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.
