Tantalum Capacitors

A tantalum capacitor is a special type of electrolytic capacitor, and is one of the most popular non-polarized capacitor types in use today. It is also known as an electrochemical capacitor, or an electrolytic or tantalum electrolytic capacitor.

Tantalum capacitors have several advantages over other types of capacitors, such as the ability to store more energy, the ability to operate over a wide temperature range and their long shelf life. In addition, they are also corrosion-resistant, making them suitable for use in both high-reliability and harsh environmental applications.

293D335X0025B2TE3 application field and working principle

The 293D335X0025B2TE3 is an axial leaded, ceramic disc type capacitor with 25V DC working voltage. It is used in various consumer and industrial applications such as AC motor drives, consumer electronics, LCDs, PDAs, computers and communication systems. Its high-temperature performance, low leakage current and long life make it well-suited for these applications.

The capacitor consists of a cylindrical strip of ceramic, commonly referred to as the dielectric. The strip is encased in a metal or polymer bag, which serves as the conductive plate and capacitor body. Electrodes in the capacitor have a coating of manganese dioxide and are in contact with the dielectric. The electrodes can be either axial or radial in design.

Upon application of a voltage, charge builds up on the conducting plates of the capacitor, forming an electrical field between the two. This field causes an ionic current to flow through the dielectric which counteracts the voltage applied, allowing the capacitor to act as a variable resistance. This results in a widened transmission gap, allowing signals to more easily pass through.

Tantalum capacitors are ideal for devices that require high-reliability performance, as their robust design ensures a long lifespan. They are also used in applications where a small size is needed, as their compact design allows for a large storage capacity.

The 293D335X0025B2TE3 is a reliable and cost-effective choice for a wide range of consumer and industrial applications. Its robust construction, long life and wide temperature range make it an excellent choice for use in high-reliability applications.
