Tantalum Capacitors

T494V107K016AT type is a kind of tantalum capacitors. It is widely used in the field of military and aerospace because its small size and light weight in comparison with other capacitors.

Applications of T494V107K016AT type Tantalum Capacitor

The T494V107K016AT type can be used in various fields due to its small size and weight, high dielectric strength and long working life. Such as in military and aerospace, telecommunication, navigation system, satellites, radar systems and so on, where it can be used for voltage suppression, energy storage and power conversion. Other applications are timing devices, oscillators and pulseforming circuits, such as switching power supplies, DC-DC converters, satellite communication systems and E-bombs.

Principle of Working of T494V107K016AT tantalum capacitor

The T494V107K016AT type tantalum capacitor works on electrolytic principle. Basically, this type of capacitor consists of two metal plates made up of tantalum. One plate is aluminum base and another plate is titanic acid compound. These plates are separated by a thin layer of oxides of tantalum which helps to conduct electricity. The plates are then placed in a solution consisted of water, alcohol, and a mixture of ammonium salt. This forms a chemical reaction in which electrons flow from the aluminum plate to the titanic acid layer. This creates a field of electric energy between two plates which is used to store electrical energy.

The positive pole electrode of the tantalum capacitor is usually made of aluminum foil and is oxidized by the surface of tantalum to become a very thin oxide film. While the negative pole is made of titanic acid compound and is oxidized by the surface of tantalum to form conductive oxide. When a voltage is applied across the two plates, an electric field is formed between them. This field produces an electric current that charges the capacitor.

The capacitance of the T494V107K016AT capacitor is determined by the thickness of the dielectric or tantalum oxide layer between the two electrodes. Increasing this thickness increases the capacitance of the capacitor. Its leakage current is usually very small and the capacitance is stable at low temperatures, making it suitable for use in low temperature environments.

Conclusion

The T494V107K016AT type of tantalum capacitor is widely used in various fields. It is mainly used in military and aerospace applications as a voltage suppression, energy storage and power conversion device. It works on electrolytic principle and its capacitance is determined by the thickness of the oxide layer. It is a very good choice in applications where low temperature and small size is important.
