Tantalum capacitors are a broader type of electrolytic capacitors, which are composed of tantalum powder as an anode, an oxide layer as a dielectric layer, and a manganese dioxide cathode. T495V157M010ATE200, as one such type of tantalum capacitor, is used in various applications. Below, we will discuss the application fields and working principle of the T495V157M010ATE200.

Application Fields

T495V157M010ATE200 capacitors are widely used for various applications, such as board-level decoupling, impedance reduction, timing control, filtering, bypassing, pulse encoder or decoder, crystal oscillator, sample and hold circuits, power supply voltage generators, and TV/monitor tuners. Furthermore, it can also be used as an energy storage system, such as backup power supply, constant current source, constant voltage source, and constant power source.

Working Principle

The T495V157M010ATE200 capacitor uses a tantalum anode, an oxide layer as a dielectric layer and manganese dioxide cathode. The working principle of this type capacitor is similar to other electrolytes, but with some differences. The tantalum anode is the negative electrode and it is surrounded by an oxide layer as a dielectric, which works as an insulating layer. The manganese dioxide cathode is the positive terminal of the capacitor, and when a reverse voltage is applied to it, electrons are attracted, which leads to the formation of a double layer of ions on the surface of the oxide layer.

The double layer window of ions works as an electrical bridge between the anode and the cathode. When a forward voltage is applied, the ions form a current path, allowing the current to flow between the two terminals of the capacitor. The total capacitance of this type is dependent on three factors: the dielectric thickness, the permittivity of the dielectric material, and the area of the electrodes. Thus, when the voltage is changed, the capacitance also changes accordingly.

In addition, the T495V157M010ATE200 capacitor offers a good temperature stability and excellent long-term reliability. These features make it ideal for use in various applications and for long-term use.

In conclusion, the T495V157M010ATE200 is a type of tantalum capacitor with various application fields. Its working principle is based on the formation of a double layer of ions on the surface of the oxide layer to establish an electrical bridge between its negative and positive terminals, and its total capacitance is dependent on the characteristics of the dielectric layer and electrodes. Moreover, because of its good temperature stability and excellent long-term reliability, it is suitable for use in various applications and for long-term use.
