1.Key points of EMC circuit filter design: L1 is a common-mode inductor, which can attenuate common-mode interference, suppress interference inside the board and external interference, improve the product’s anti-interference ability, and reduce external radiation through the 429 signal line. The common-mode inductor impedance selection range is 120Ω/100MHz ~2200Ω/100MHz, and the typical value is 1000Ω/100MHz; C1…
