A series connection of capacitors is when the end of one capacitor is connected to the start of the next capacitors. If the capacitors are electrolytic capacitor, extra care should be taken with the polarity. The + wire of the first capacitor must be connected to the - wire of the next one, like when connecting batteries in series:

The electrolytic capacitor provides higher capacitance than the electrostatic capacitor and is rated in microfarads (μF), which is a million times larger than a pico-farad. These capacitors deploy a moist separator and are used for filtering, buffering and signal coupling. ... One would have to connect about 5 super cap "cells" in series over ...
As a result, Nichicon developed and launched the GYA series of conductive polymer hybrid aluminum electrolytic capacitors, which are compatible with high temperatures, long lifetimes and high ripple currents. The GYA series uses a hybrid electrolyte obtained by combining conductive polymer and electrolytic solution.
The capacitance values have a wide tolerance range and relatively high leakage currents. The most common applications for electrolytic capacitors are as filter capacitors in both linear and switching power supplies (Figure 5). Figure 5: Examples of electrolytic capacitors; all have a capacitance of 10 microfarads (µF).

A remaining useful life prediction model for electrolytic capacitor in DC-DC converter is presented in this paper based on Neural Network method.
I need to use a capacitor in a DC circuit where it would store somewhat higher voltage (hundreds of volts). The cheapest way to do that (in my case) is to connect multiple electrolytic capacitors in series, because their maximum voltage is lower than the voltage I want to store. In theory, it should work well with non-polarized capacitors.
When capacitors are in series, the same charge passes through each. The total charge in the whole series string is the same as for one capacitor. When capacitors are in parallel, the …
Inside an electrolytic capacitor is a junction of multiple materials. The initial application of voltage in the factory chemically creates an oxide layer which is the dielectric. Reversing the voltage will dissolve the dielectric and destroy the …

The symbol with the curved line (#2 in the photo above) indicates that the capacitor is polarized, meaning it''s probably an electrolytic capacitor.More on that in the types of capacitors section of this tutorial.. Each capacitor should be accompanied by a name -- C1, C2, etc.. -- and a value.
As electrolytic capacitor is apt to fail in power converters, it is very important to monitor its electrical parameters, mainly the equivalent series resistance (ESR) and capacitance (C).
All three have a claim to making the first primitive capacitor-battery based on Leyden jars strung together. 1800: Italian physicist (and battery inventor) Alessandro Volta (1745–1827) coins the (confusing) word "condenser" for a charge-storing device. Capacitors are still sometimes known as condensors to this day, though the term has largely ...

Schematic illustration of a supercapacitor [1] A diagram that shows a hierarchical classification of supercapacitors and capacitors of related types. A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors …
Another example for the use of serially connected capacitors is a possible replacement of a car battery with a capacitor bank made of supercapacitors. Since their maximum rated voltage is only about 2.7 volts, by connecting six such supercapacitors in series, the operating voltage of the bank is raised to levels acceptable for automotive use ...
The first article in this series [1] covered the early history of electrolytic capacitors, from their invention around 1880 to the invention of the modern Al electrolytic capacitor structure in 1925. To summarize the early history, "valve metals" were recognized in the 1880s for their ability to conduct in one direction but impede current flow in the opposite …
If you can live with electrolytic capacitors, there''s a trick: their low voltage energy density is underwhelming. And, to extract most energy from them, you can''t just discharge them by directly connecting them to the load that …
Using a series connection means that voltage balancing would need to be used, when charging both supercaps and LiPos. If your load can take the voltage variation from 11 to 14 V, then an easier solution would be a lead …

Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F.
