Note: 1. Filtering capacitors C1, C2 are electrolytic capacitors, C1 is used in AC input, when input voltage is below 100VAC, the value of C1 is 22uF/400V. C2 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. C3 is ceramic capacitor, it is used to filter high frequency noise. TVS is a recommended component to protect post-circuits (if converter fails). 2. If EMC performance is required, recommended to add “EMC filter” at the input end. C4: X capacitor, recommended parameter :0.1uF/275V C5,C6: Y capacitor, recommended parameter:220pF/2000V NF: Common-mode choke, recommended parameter: 10mH-30mH 3. MOV: pressure sensitive resistance, model 471KD05, is used to protect converter in lightning strike surge.
