Note:

1. Output filtering capacitors C1, C3 are electrolytic capacitors, 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,C4 are use to filter high frequency noise，

suggest choose 0.1

µF. TVS is recommended component to protect post-circuits (if converter fails).

2. External input NTC is recommended to use 5D-9 ( Only LH10 models and LH15 models)

3. Module recommended external varistor，model：S10K550。

4. If common requirement to EMC performance, refer to figure 1& figure 2, if higher requirement to EMC performance, refer to figure 3.

µF /275V;

C6,C7:Y capacitor, recommended parameter 2200pF/400V;

NF: common model choke, recommended inductance is about 10mH-30mH.
