In a lot of PCB design, I found that many friends have problems with the filter capacitor wiring, so I made a few diagrams to illustrate, hoping to help you.
The figure is a wrong filter capacitor connection, the power supply should be directly from the capacitor to the IC, the filtering effect will be good.
The following is the correct connection.
In this way, the filtering effect will be much better.
If you don’t think it’s good-looking, it’s right to deal with it according to the figure below. You can also find that the following processing method is also used in some PCB designs.
