OverviewGeneral informationTypes and features of electrolytic capacitorsHistoryElectrical characteristicsOperational characteristicsCauses of explosionAdditional information
As to the basic construction principles of electrolytic capacitors, there are three different types: aluminium, tantalum, and niobium capacitors. Each of these three capacitor families uses non-solid and solid manganese dioxide or solid polymer electrolytes, so a great spread of different combinations of anode material and solid or non-solid electrolytes is available.
Tantalum vs Aluminum Capacitors: Making the Right Choice
One important aspect of electrolytic capacitors is the dielectric material they use, which can be solid or non-solid. High-end motherboards often prefer solid capacitors made from aluminum, tantalum, or polymer.

Types of capacitors and how they are made
Aluminum electrolytic capacitors are famous for their low cost and ability to hold large amounts of energy in a small package compared to ceramic or film capacitors. While electrolytic capacitors are very popular, they are more sensitive to unwanted voltages and temperature than other capacitors and have relatively high current leakage.
Afraid of aging? The effects of time on electrolytic capacitors
After the aluminum electrolytic capacitors have been mounted on the printed circuit board, the increased leakage currents must be taken into account, e.g. in the first startup of the device, and the electrolytic capacitor must be given time to regenerate. If these
Explaining Capacitors and the Different Types | DigiKey
On one of the foil sheets (in standard Aluminum electrolytic capacitors) a layer of aluminum oxide is formed that serves as the capacitor''s dielectric material by applying a voltage to the foil through an oxygen-bearing electrolyte solution.

The modern era of aluminum electrolytic capacitors
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 …

Aluminum Electrolytic Capacitor: Structure and Features
Aluminum electrolytic capacitors are electrolytic capacitors with polarity. They are made of an aluminum cylinder as the negative electrode, filled with liquid electrolyte, and inserted into a bent aluminum strip as the positive electrode. It also needs to undergo DC voltage treatment to form an oxide film on the positive electrode as a …
