What capacitors should be used to prevent harmonics

The Fundamentals of LDO Design and Applications

Any good quality ceramic capacitors can be used, as long as they meet the minimum capacitance and maximum effective series resistance (ESR) specifications listed on the LDO data sheet. Ceramic capacitors using X5R or X7R dielectrics are highly recommended as these have good temperature stability and a low voltage coefficient.

How to get rid off the harmonics in electrical system?

Higher-frequency harmonics can be propagated by the power conductors acting as antennae and appear as induced noise voltages in nearby signal circuits. It is not possible to prevent harmonic currents altogether. But they can be prevented from flowing through the entire system by providing a separate low-impedance path for them. This is done by
