Tantalum Capacitors: T491D476M016AT4153 application field and working principle
Tantalum capacitors are widely used in electronic applications because of their extended 30 circuits reliability, long-term stability and cost effectiveness. T491D476M016AT4153 is a type of tantalum capacitors featuring high voltage and widely used in a variety of electronic devices, such as computers and mobile phones. This article will discuss its application fields, and introduce the working principle of tantalum capacitors.
Application Field
T491D476M016AT4153 are widely used in high-voltage applications due to their excellent performance at high level voltages. Unlike aluminum electrolytic capacitors, they can withstand high voltage shocks such as those encountered on the grids of distributed power supplies in automotive, industrial and aerospace applications. Furthermore, the long-term life and stability of T491D476M016AT4153 capacitors also make them suitable for applications where low frequency ripple or random electrical fields are needed. For example, they can be used for power management as well as for signal filtering applications.
Working Principle
Tantalum capacitors are one type of non electrolytic capacitors formed by an anode made of tantalum, a dielectric material, an electrolyte solution and a cathode, usually an oxygen free high conductivity cathode. The dielectric is formed by the oxide layer on the anode surface. When voltage is applied across the anode and cathode of the capacitor, a charge builds up and creates a field of energy between them. This is the basic principle of operation of a tantalum capacitor. The capacitance of a tantalum capacitor is determined by the size of the anode and the thickness of the oxide layer, as well as the area of the two metallic electrodes. In comparison to other types of capacitors, tantalum capacitors offer low leakage currents, long-term reliability and superior temperature stability.
Conclusion
T491D476M016AT4153, with its high voltage rating and long-term stability, is a type of tantalum capacitors suitable for high-voltage applications. It is also effective for power management and signal filtering. The operational principle of tantalum capacitors relies on the forming of an oxide layer on its anode, the electrodes size and the type of the liquid electrolyte solution.
