C1:AC input, is filtering electrolytic capacitor (which is required), when input voltage is below 100VAC, and the value of C1 is 22μF/400V. DC input, is a filtering capacitor in EMC Filter, the value of C1 is 10µF/400V(when input voltage is above 370VDC, and the value of C1 is 10µF/450V), If EMC performance is not required,C1 could not need. 2. C2 is ceramic capacitor, it is used to filter high frequency noise. Output filtering capacitor C3 (which is required when AC input or DC input) 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. TVS is a recommended component to protect post-circuits (if converter fails). External input NTC model is recommended to use 5D-9. External input MOV model is recommended to use S14K350. 3.
