Modeling Dielectric Absorption in Capacitors

dielectric absorption. The amount of dielectric absorption a capacitor exhibits is highly dependent on the dielectric material: polystyrene, polypropylene, and teflon display very little absorption, while ceramic is a much poorer performer. SiO2 displays about 0.1% dielectric absorption, putting its performance in the middle of the pack [12,16].

Quantifying the piezoelectric effect of ceramic capacitors

The physical size of the capacitor is definitely a factor, as is the dielectric. To mitigate this, if possible ceramic caps should be placed in pairs on opposite sides of the PCB in the same exact X-Y location. (I.e. if you need 200uF use 2 100uF caps in parallel, one on the top side and one on the bottom.)

A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications. Ceramic capacitors are divided into two application classes:
