Note:

1. Output filtering capacitors 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. Voltage derating of capacitor should be 80% or above. C1 is ceramic capacitor. it is used to filter high

frequency noise. TVS is a recommended component to protect post-circuits (if converter fails).

2. For standard EMC requirement, please refer to figure 1 to figure 4.If higher EMC requirement , please refer to figure 6（LH40-10Axx/LH40Dxx/LH40-10Cxx Adjust the

corresponding output circuit）, recommended parameters are shown in the table below.
