Note：
1. Output filtering capacitors C1, C3 is electrolytic capacitors, It is recommended to use high frequency and low impedance electrolytic capacitors. For capacitance
and current of capacitor please refer to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. C2 is ceramic capacitor, it is used to filter
high frequency noise. TVS is a recommended component to protect post-circuits (when converter fails).
2. MOV is required to LD03 models，model: 471KD05, it is used to protect the device under surge.
3. It is recommended to connect FUSE, the parameter for LD03 models is 0.5A/250V slow blow, for LD05 models is1A/250V slow blow. External input NTC is
recommended to use 5D-14 or 10Ω/2W wire-round resistor.
4. If EMC performance is required, recommended to add “EMC filter” at the input end(see figure 3,4)
C6:X capacitor, recommended parameter 0.1uF/275V;
C7,C8:Y capacitor, recommended parameter 220pF/2000V;
NF: common model choke, recommended inductance is about 10mH-30mH.
5. LD03 models: Terminals 22 and 26 are internal rectification and filtering terminals. To protect the models further, it is recommended to connect an electrolytic
capacitor C3 (it is recommended to be 4.7uF/400V). If operation voltage of the module is between 160~264VAC, C3 can be removed.
