Note:
① . series with suffix “H” are heat sink mounting,for example URB2405D-30WHR2 is with heatsink, URB2405D-30WR2 is without heat sink.
If the application has a higher requirement for heat dissipation, you can choose modules with heat sink.
②. Absolute maximum rating without damage on the converter,but it isn't recommended.
③ . For dual output converter, the given value is the same for each output.

DESIGN CONSIDERATIONS
1)Recommended circuit
All the URA_D-30WR2 & URB_D-30WR2 Series have been tested according to the following recommended test circuit before leaving
the factory (see Figure 4).
If you want to further decrease the input/output ripple, you can increase a capacitance-values properly or choose capacitors with low ESR,
but the total capacitance of the filter capacitor must not exceed the Max. Capacitive Load.
Recommend external capacitor see table 2.

Note:
1. Min. load shouldn't be less than 5%, otherwise ripple maybe increased dramatically, If the product operates under min. load, it may not be
guaranteed to meet all specifications listed. Operation under minimum load will not damage the converter.
2. Recommended Dual output models unbalanced load is ≤±5%, If the product operates >±5%, it may not be guaranteed to meet all specifications
listed. Please contact our technical support for more details.
3. Max. Capacitive Load is tested at input voltage range and full load.
4. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
5. In this datasheet, all test methods are based on our corporate standards.
6. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more details.
7. Please contact our technical support for any specific requirement.
8. Specifications of this product are subject to changes without prior notice.
