I think there should be no problem with the size of the front and rear capacitors. There is no noise on the circuit board without a load. After a small load is connected, there will be even currents. How can I solve it? ? ?

Sizzle? Is it a horn? Please list your 12V power supply and load. In addition, your circuit diagram 100nF/6.3V is wrong.

What load and how much power?

The load is connected to a 0.96 inch screen module, and its current is only 6MA, ah, there is no problem if you don't connect it.

The picture still has some problems.
