Notes: Derating Curve
1. Output load regulation is specifi ed for a load change of 10% to 100%.
2. When measuring output ripple, it is recommended that a 1 µF capacitor and a 10 µF capacitor be placed
in parallel from each output to common.
3. It is recommended that the minimum output load should be at least 10%. Operation below this level will
not damage the unit, but it may not meet all specifi cations..
4. These converters are specifi ed for operation without external components. However, in some applications
the addition of input/output capacitors will enhance stability and reduce output ripple. The simple connection
shown below will typically meet EN 55022 Class B.

5. The recommended refl ow settings are a peak temperature of 245 °C for a 4 Common 10 NC
maximum period (TPK) of 10S and a time above liquidous (TL) of <60 seconds Mechanical Dimensions
at 217 °C. For more information, please contact the factory. NC = No Connection
6. It is recommended that a fuse be used on the input of a power supply for
protection. See the Model Selection table above for the correct rating.
