External electrolytic capacitor are required to models when AC input, more details refer to typical applications.
Ripple and Noise were measured by the method of anear measure (more details refer to the anear measure).
All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
In this datasheet, all the test methods of indications are based on corporate standards.

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.
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).
Recommended external circuit parameters in Figure 3:
