Note:
1. Due to limited space, the above is only a list of typical products. If you need products outside the list, please contact our sales department.
2. The maximum capacitive load indicates the maximum capacitive load that + Vo or -Vo can connect to. If it exceeds this value, the product will not start normally.

Notes：Output Load Requirements
In order to ensure that the module can work efficiently and reliably, the minimum output load should not be less than 10% of the rated load.If the power you need is really small, please connect a resistor in parallel between the positive and negative poles of the output terminal (the sum of the actual power used by the resistor is greater than or equal to 10% of the rated power and the rated power of the selected resistor must be greater than 5 times of the actual power used, otherwise the temperature of the resistor will be higher)
