In commercial applications, the two main types of capacitors frequently utilized are electrolytic and tantalum. Electrolytic capacitors are widely known for their high capacitance values and are often used in power supply filters, decoupling applications, and coupling circuits. They can handle significant voltage and are distinct due to their polarized nature, which means they must be installed in the correct orientation in a circuit.

Tantalum capacitors, on the other hand, also offer high capacitance values and are notable for their small size and stable performance across a range of temperatures. They are used in applications where space is limited and reliability is crucial, such as in portable electronics, medical devices, and military applications.

While oil-filled capacitors do have specific applications, they are not as commonly employed as electrolytic and tantalum capacitors in the broader commercial market. Ceramic capacitors, while popular, usually cater to lower capacitance requirements compared to the higher capacity needs addressed by electrolytic and tantalum types. Film capacitors, such as polyester, also serve specific niches but do not account for the majority use in commercial settings as the other two types do.
