Note:
1. Output filter capacitors C2, C4 are 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. C1, C3 are ceramic capacitors, used to
filter high frequency noise，suggest choose 1µF. TVS is recommended component to protect post-circuits (if converter fails)
2. External input NTC is recommended to use 5D-9
3. For standard EMC requirement, please refer to figure 1 or figure 2, if higher EMC requirement ,please refer to figure 3
FUSE：LH10/15 recommended to use 2A/250V，LH25 recommended to use 3.15A/250V
