What is the Use of a Decoupling Capacitor? | Sierra Circuits
The X7R-type ceramic capacitor is preferred because it shows less change in capacitance as a function of DC bias voltage compared to Z5U and Y5U. Additionally, NP0 (COG) ceramic capacitors (0.1 μF or less) are also used because of their lower dielectric constant formulation and low voltage coefficient.

Capacitor Basics: How do Capacitors Work?
In a DC circuit transient, where you''re modeling a switch opening or closing, a capacitor will resist the change in voltage. This resistance is because the current that is flowing into the capacitor is "filling" the capacitor up, it can''t charge or discharge instantaneously. This change in voltage is consistent and can be calculated ...
