Typical Application Circuits
EMC parameter recommendation
| Component No. | Function | Recommended value |
| Fuse | Protest the circuit from damage when the module is abnormal | 2A/250Vac, Slow fuse |
| Varistor | The cumulative surge is to protect the module from damage | 10D561K |
| C1/Safety capacitance | Filtering, safety protection(EMC certification) | 0.1uF/275Vac |
| L1/Common-mode inductance | EMI filtering | Sensible value 10-20mH, current 1-2A |
Notes：
* Fuses and varistors are basic parts of protection circuits (required).
* If the certification is required, the safety capacitor and common mode inductance cannot be omitted.
Output filtering
For usual requirements of ripple and noise, the peripheral recommendation is only C2; For strict requirements of ripple and noise, the above circuit is recommended. Notes:
(1) C2, C3 use high frequency low resistance electrolytic capacitor, and the total capacity can not exceed the maximum capacitive load indicated in the manual, otherwise the module will not start normally. (2) When the capacitive load is used, the minimum load of 3% must be guaranteed, otherwise the module output will be abnormal.
| Component No. | Function | Recommended value |
| LDM3/Common mode inductance | Adjust the output ripple voltage | Inductance: 0.47-4.7uH according to the debugging result |
| LDM4/Common mode inductance | Adjust the output ripple voltage | Inductance: 0.47-4.7uH according to the debugging result |
| C2,C3 Electrolytic capacitor | Ripple voltage filtering | 68-220uF/50V |
| C4 Ceramic capacitors | Ripple voltage filtering | 1uF/50V |
