 Cin CapacitanceFilter capacitor4.7μA/50V

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)
