Note:
Output filtering capacitor C2 is a 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. Output capacitor withstand voltage derating should be 80% or
above. C1 is ceramic capacitor, which is used to filter high-frequency noise. External input NTC
is recommended to use 12D-5; External input MOV is recommended to use S14K350.
