Notes: 1. 20 MHz bandwidth oscilloscope, 10% to full load, the output is in parallel with 10µF electrolytic capacitor and 1µF ceramic capacitor. 

2. For optimal performance, it is recommended to operate at a load of above 5%. 

If the load falls below 5%, the ripple index of the product may exceed specifications; however, this does not impact the product’s reliability. 

3. All specifications are measured at Ta=25°C, humidity <75%, 115 or 230 Vac input voltage, and rated output load unless otherwise specified.

- Note:   1. FUSE, EMC protection, and EMI protection are selected based on actual application needs. 

2. C1 is a filtering electrolytic capacitor, which is a required component. It is recommended to use ripple current> 400mA at 100KHz electrolytic capacitors. 

3. C2, C4, and L1 form a Pi type filtering circuit, and it is recommended to use high-frequency low resistance electrolytic capacitors or solid-state capacitors. When selecting L1, ripple requirements can be considered, while paying attention to current and internal resistance values. 

4. L1 selection can take into account the ripple requirements, while paying attention to current and internal resistance values.
