Notes:   1. Ripple & noise are measured at 20 MHz BW, with 10µF electrolytic capacitor and 1µF ceramic capacitor. 

2. It is recommended to use at a load of over 5%. If the load is below 5%, the ripple index of the product may exceed the specifications, but it does not affect the reliability of the product. 

3. Unless otherwise specified, all indicators in this manual are measured at Ta=25 °C, humidity<75% RH, nominal input voltage, and output rated load.

Notes:    1. Fuse and MOV should be selected based on application requirements and performance criteria. 

2. D1 is a TVS transistor that can protect the downstream circuit in case of module abnormalities. It is recommended to choose a model that is 1.2 times the output voltage.
