Output filtering capacitor C1 is an electrolytic capacitor. 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. 2. It is recommended to use a 1A/250V slow blow FUSE. External input NTC is recommended to use 5D-14 or 10Ω/2W wire-round resistor. 3. If EMC performance is required, it is recommended to add “EMC filter” at the input end (see EMC Application Figure). C6: X capacitor, recommended parameter 0.1μF/275V; C7,C8: Y capacitor, recommended parameter 2200pF/400V; CY:Y capacitor, recommended parameter 102K/400V NF: common model choke, recommended inductance is about 10mH-30mH.
