For capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitance withstand voltage derating should be 80% or above. C1 is ceramic capacitor, which is used to filter high-frequency noise. TVS is a recommended component to protect post-circuits if converter fails. External input FUSE model is recommended to use 3.15A/250VAC, slow fusing. External input NTC model is recommended to use 5D-9. External input MOV model is recommended to use S10K300. 2.
