Tantalum Capacitors

Tantalum capacitors are one of the most important components in modern electronic circuits, thanks to their wide array of uses, small size, and relatively low cost. They are made of solid-state electrodes and are used for energy storage, signal processing and noise reduction. One of their most popular varieties is the TPSA335K020R2500.

Application Field

The TPSA335K020R2500 is a surface-mount tantalum capacitor, which makes it great for any project relying on a compact design. It is commonly used in audio, signal processing, and radio frequency applications, where its high volumetric efficiency and low equivalent series resistance (ESR) are of utmost importance.

They are also found in medical, automotive and military equipment, especially when size and reliability are desired. In addition to being reliable, they are also highly durable, able to operate at a wide temperature range (from -55°C to 125°C).

Working Principle

Tantalum capacitors have an anode, cathode, and dielectric all made of solid raw material. When connected, the anode forms an electric field with the cathode, which is blocked by the dielectric. This charge is then stored, and can be released when the capacitor is disconnected. The size of the capacitor determines the amount of charge it can hold, which is measured in farads.

TPSA335K020R2500, like all tantalum capacitors, relies on a tantalum anode and an electrolytic, manganese dioxide cathode. It is available in a 4-terminal wrap-around case, and is equipped with a soldering pin for easy integration in circuit boards. Its high-temperature reliability makes it an excellent choice for many demanding applications.

Thanks to their small size, reliability and low cost, tantalum capacitors like the TPSA335K020R2500 are widely used in commercial and military electronic devices, from audio amplifiers to avionics systems. Their range of applications makes them a highly sought after type of capacitor.
