Ripple and noise test method, Twisted pair test method, can add capacitive load at the output to reduce light load ripple Typical Application Circuits EMC parameter recommendation Component No. Function Recommended value Fuse Protest the circuit from damage when the module is abnormal Access the corresponding fuse accrding to customer needs MOV1/Varistor Protest the circuit from damage when the module is abnormal 14D333K LDM1/Common mode inductance EMI Filtering Inductance: 2mH CO,C1 Ceramic capacitors Filter capacitor 1uF/100V E1,E2 Electrolytic capacitor Filter capacitor 100uF/100V LDM2/Differential mode inductance EMI filtering 4.7-68uH CY1/Y2 Capacitance 1nF/250vAC 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.
