There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors. Dielectric capacitors encompass film capacitors, ceramic dielectric capacitors, and electrolytic capacitors, whereas supercapacitors can be further categorized into double-layer capacitors, pseudocapacitors, and hybrid capacitors.
While an ideal capacitor would have no internal resistance, real-world capacitors do. This internal resistance is known as Equivalent Series Resistance (ESR). ESR represents the combined resistance of various components within the capacitor, including: Electrode Resistance: The resistance of the conductive plates.
Personally, and as a general rule and for repairs of medium quality, cheap things, if the capacitor I am going to use has a maximum ESR of twice what it says in the table, I'll take it for granted. The quality of the capacitors in a switched-mode power supply largely determines the quality of the power supply itself.
There are specific ESR meters that are available in the market which can be useful to measure the ESR of a capacitor. These meters use Alternating current, such as square wave in a specific frequency across the capacitor. Based on the change in frequency of the signal the ESR value of the capacitor can be calculated.
A simple energy storage capacitor test was set up to showcase the performance of ceramic, Tantalum, TaPoly, and supercapacitor banks. The capacitor banks were to be charged to 5V, and sizes to be kept modest. Capacitor banks were tested for charge retention, and discharge duration of a pulsed load to mimic a high power remote IoT system.
An ideal capacitor in series with resistance is called Equivalent series resistance of the capacitor. The equivalent series resistance or ESR in a capacitor is the internal resistance that appears in series with the capacitance of the device. Let's see the below symbols, which are representing ESR of the capacitor.
