EMC recommendation circuit
F1 selects 1A/300Vac's slow fuse, RT1 and RV1 are thermistors and varistors, respectively. The flow rate of the varistor shall be no less than 3KA, and the voltage is 500V to 650V.
The main functions of L1, L2, CY1, CY2 and CX1 are to filter the differential mode and common mode interference on the line. For this product, L1 takes 4.7 H and L2 takes the inductance of 2.2mH as the common mode inductance. CY1, CY2 take 1nF/400Vac, CX1 take 0.1 mu F/400Vac. C1 is a ceramic capacitor that removes high-frequency noise and the C2 is a high frequency, low resistance electrolytic capacitor.
