Tantalum Capacitors

Tantalum capacitors are widely used in electronics and are ubiquitous in industry applications. They are found in a variety of products including linear and high-voltage switched-mode power supplies, computers, digital cameras, LCD monitors and countless other consumer electronics. The TACR336K004XTA is an example of a tantalum capacitor, and its application field and working principle are discussed below.

Application Field

The TACR336K004XTA is a highly reliable, low-ESR type multi-anode tantalum capacitor suitable for use in high current, high voltage applications. It is especially well suited for use in products such as mobile phones, PDAs, cameras and LCD monitors, where it helps to effectively reduce the ripple voltage and interference generated in switching power supplies. It is compact, highly reliable and offers excellent performance under extreme temperatures and operating conditions. Furthermore, its low-ESR construction allows for increased ability to handle higher currents.

Working Principle

Tantalum capacitors, including the TACR336K004XTA, are “electrolytic”, which means that the anode is composed of a tantalum oxide dielectric and the cathode is made up of an aluminum oxide oxide dielectric. When a voltage is applied, the oxide dielectric layers are polarized such that one becomes positive and the other negative. This creates an electrostatic potential between the two layers, thus allowing the capacitor to act as a electrical storage device. The capacitance of the device is determined by the area, thickness and permitivity of the oxide layers, along with the distance between the anode and cathode.

In addition to the capacitive action, the TACR336K004XTA also features a protective film coating that helps to protect against oxidation and corrosion, as well as providing protection against short circuits. The capacitor also features a unique, low-ESR construction, which helps to improve its ability to handle high currents and reduce power losses.
