2) Where isolation is necessary between input and
output(Isolation voltage≤1500VDC);
Note: Metal package style series is WRA_YDV-3W & WRB_YDV-3W.
3) Where the regulation of the output voltage and the
output ripple noise are demanded.

APPLICATION NOTE
Requirement On Output Load
In order to ensure the product operate efficiently and reliably, in addition to a max load(namely full
load), a minimum load is specified for this kind of DC/DC converter. Make sure the specified range of input voltage is not
exceeded, the minimum output load no less than 10% load. If the actual load is less than the specified minimum
load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly. If the actual output power
is very small, please add an appropriate resistor as extra loading, or contact our company for other lower
output power products.
Recommended Circuit
All the WRA_YDV-3W & WRB_YDV-3W Series have been tested according to the following recommended testing circuit
before leaving factory. This series should be tested under load. Never be tested under no load (see Figure 1).
If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with

low ESR. However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big,
a
startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the
greatest capacitance of its filter capacitor sees (Table 1). Generally: If you want to use the products in high EMI, please choose

Input Current
When it is used in unregulated power supply, be sure that the fluctuating range of the power supply and the rippled
voltage do not exceed the module standard. Input current of power supply should afford the startup current of
this kind of DC/DC module (See figure 2), General:

RECOMMENDED FOOTPRINT
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℃, 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.
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.
