Electrolytic capacitors are a specific type of capacitor that utilizes an electrolyte to achieve a larger capacitance compared to other capacitor types. These capacitors are particularly effective in reducing voltage and mitigating voltage fluctuations. They find prominent use in DC power supply circuits due to their capacity for providing substantial capacitance in a compact size, effectively reducing ripple voltage.

The primary types of electrolytic capacitors include aluminum electrolytic capacitors, tantalum electrolytic capacitors, and niobium electrolytic capacitors. Tantalum capacitors, a subtype of electrolytic capacitors, are constructed with tantalum metal serving as the anode. This is covered by a layer of oxide, which acts as the dielectric, and surrounded by a conductive cathode. Tantalum capacitors are applied across a range of applications, including power generation, transmission, distribution, and various sectors such as consumer electronics, industrial electronics and lighting, computers and telecommunications, energy, as well as automotive and aerospace, including defense applications.Asia-Pacific was the largest region in the electrolyte capacitor market in 2025.
