When I was designing recently, I used 0.1μf capacitors for the power filter circuit, but someone told me to use 0.01μf capacitors. This is why, don't general circuits use 0.1μf capacitors?

Power supply filtering requires large capacitors with small capacitors.

0.1uf is generally placed close to each pin; as for why 0.1 is used, it is because the capacitance of this value is the most commonly used, and each manufacturer produces the most;

It depends on the working state of the circuit, including the nature of the load, and different states have different requirements for the power filter frequency, so different capacities are used.

Small-capacity capacitors also have different requirements for the welding arrangement position in the actual circuit, and it is generally required to be as close to the chip end as possible.
