In practice, capacitors aren't completely linear. You can make a decent guess at the ESR, which lets you engineer for the range the ESR might be, but you won't

31.03.2017Equivalent series resistance (ESR) is one of the non-ideal characteristics of a capacitor which may cause a variety of performance issues in electronic circuits. A high ESR value degrades the performance due to I 2 R losses, noise, and higher voltage drop. In some applications, the heat generated due to ESR is small and may not be an issue.

Ceramic capacitors have low ESR and low ESL characteristics. Therefore, the impedance of a ceramic capacitor (22uF/6.3V/0603size) is smaller than that of a Ta-Cap (100uF/6.3V/1206size) over 100kHz range. Thus, the ceramic capacitor has a better noise suppression effect at a high-frequency range.
