A parallel resonant circuit has a resistor, an inductor, and a capacitor in parallel, as shown below. In either case, the resonant frequency is given by: ω 0 = 1/√ LC.

Parallel capacitor with different values and how to use them
It''s common to use the small ones to filter out high-frequency noises. It is all because the capacitors are not ideal. An ideal big capacitor must filter any noise bigger than the cut-off frequency of the circuit. The higher the frequency, the better filtration. However, the big capacitor does not work well at higher frequencies in the real world.
