Tolerances: ±0.50mm [0.020in]
1. If use of heat sinks, make sure there is
enough space for a specific size in the above
graph.
2. Products will be supplied with heat sinks
already mounted, separate heat sinks are not
available.
In order to obtain better performance for the
DC/DC models, it is recommended to use
input and output filters as shown.
Note:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output unless otherwise specified.
2. Capacitor Max. load tested at nominal input voltage, full load and constant resistive load.
3. Only typical model listed. Non-standard models will be different from the above, please contact us for more details.
4. In this datasheet, all the test methods of indications are based on corporate standards.
The CTRL control pin voltage is referenced to GND
