    Cautions when arranging noise suppression parts

    NaMo_1534561

      Hello,

       

      Customers are trying to place ferrite beads in the VDD and GND wiring as a noise countermeasure on the power supply line where switching power supplies are generated.

      A bypass capacitor is already placed in the circuit. (0.1uF and 1uF for Vdd, 0.1uF for Vccd)

      Are there any cautions on the circuit layout regarding the placement of bypass capacitors and ferrite beads?

      Best Regards,
