T494R106K010AT belong to tantalum capacitors, which accompanied by a broad range of uses and forms. These types of capacitors are most often used in power supplies, decoupling applications, circuits applying high levels of ripple current as well as circuits with very high impedances. Tantalum capacitors have a nominal capacitance when measured at 1kHz, volumetric efficiency that is more often incomparable to any other capacitor types and enjoy good temperatures stability characteristics.

T494R106K010AT is a kind of surface-mounted tantalum capacitors that are highly appreciated by many customers for its safety, efficiency, tiny form, long lifespan, and extremely small leakage. It is normally built with a anode made out of a sintered anode powder and an internal cathode made from Titanate or Tantalum material. Commonly, its external packaging is in encapsulated resin.

The further logic of these capacitors is that the internal dielectric layer to provide the capacitance. The dielectric layer can be either Ta2O5 or niobium oxides that are constructed in an ionic lattice structure. This structure gives the capacitor a higher ratio of capacitance to volume than, for example, an electrolytic type capacitor.

As for its working principle, it is based on Faraday’s theory of capacitance, meaning the capacitance of a system depends on the intersection area between the two electrodes, as well as the layer of dielectric material separating them. When a voltage is applied across the two electrodes, a electric field and surface charge will be created, thus stimulating an electric field between the two features. The capacitor’s capacitance will then be decided by the intersection area, the type and thickness of dielectric layer, and the electric field.

More importantly, tantalum capacitors are widely used in some of the most demanding applications because of their relatively low equivalent series resistance (ESR), since it enable the capacitors to handle extremely high ripples current. ESR also affect the time constants of a capacitor, meaning, the capacitors, in this case the T494R106K010AT, will be slowly depending on its values.

To conclude, T494R106K010AT, a surface-mounted capacitors that belongs to tantalum capacitor, comes with along with a range of features and peculiarity characteristics such as good volumetric efficiency, good temperature stability, and the capability to handle high ripple current and external packaging encapsulated resin. Its capacitance functions refer to Faraday’s theory that highlights its intersection area between the two electrodes, thickness of dielectric layer, and the electric field. By understanding its working pacticles, customers are now able to choose one of these capacitors, depending on the specific needs that the application will require.
