Tantalum Capacitors

T491B474M050AT42547280 is a type of tantalum capacitor. It is a type of electrolytic capacitor, different from the traditional ceramic or film capacitors. In its core, tantalum capacitors are composed of two electrodes film-composed with one layer of an electrolyte and a dielectric tantalum pentoxide film. When it is energized, it becomes a capacitor that acts as a charge-storage device.

Application Field

T491B474M050AT42547280 has numerous applications in a wide range of industries and products. In devices dealing with high-frequency signals, the very low inductance construction of tantalum capacitors enables them to be used in power supplies and noise suppression applications. The tantalum capacitor also offers a much higher capacitance-to-volume ratio than alternative technologies, especially for surface mount configurations. As such, tantalum capacitors are commonly seen in system clocks, LED controllers and power management systems.

Due to its low-profile design, its reliable performance and a wide variety of capacitance values, the tantalum capacitor is a great choice for filtering, decoupling and bypass scenarios. Its superior volumetric efficiency is superior even to other electrolytic components - this is why it has become the preferred choice in power electronics and miniaturized circuits. In addition to its electronics-related applications, it can be used for audio and video signals, telecom equipment, automotive systems, medical equipment and more.

Working Principle

T491B474M050AT42547280 works on the same principle as other electrolytic capacitors. Its construction is similar to other electrolytic capacitors, whereas its core is made up of two aluminum layers separated by an intervening electrolyte layer, in which a tantalum pentoxide film is laid as a dielectric. The application of an electric field causes the movement of cations and anions through the electrolyte, resulting in the formation of an electric double-layer.

The flow of current between the two electrodes is regulated by the electric double-layer, which can take on more charge with increased voltage. This regulated flow of current is the main advantage of using such a capacitor for the storage of electrical energy. The very low inductance construction of tantalum capacitors enables them to be used in power supplies and noise suppression applications.

T491B474M050AT42547280 tantalum capacitors are widely used in a wide variety of industries, due to their evident advantages over traditional ceramic and film capacitors. The tantalum capacitor is slightly more expensive than its counterparts, but its efficiency and flexibility render them an ultimate choice in high-frequency applications.
