Tantalum - Polymer Capacitors

Tantalum-Polymer capacitors, also known as polarized capacitors, are a family of electrical components that can be used to store electric energy. They are one of the most commonly used components in the field of electronics and are widely used in a variety of applications. The TCJY156M025R0090 is a specific type of Tantalum-Polymer capacitor that is well known for its high capacitance and reliability. This article will discuss the application field and working principle of TCJY156M025R0090.

Application Field of TCJY156M025R0090:

The TCJY156M025R0090 is generally used in Digital Audio and Video products, mobile phones, notebook computers, and other electronic products such as memory protection and high frequency switching power supply. It can also be used for automotive audio and power supply applications, computer peripheral products, instruments, meters, digital cameras, and audio equipment. Furthermore, the TCJY156M025R0090 is used in various applications that require a temperature compensation, high stability, and high frequency operation. The high capacitance and low ESR of this specific capacitor also make it suitable for power supply decoupling, oscillator timing circuits, and several other electronic applications that involve frequency noise damping or AC power filtering.

Working Principle of TCJY156M025R0090:

The working principle of the TCJY156M025R0090 is based on the fact that electric charges are stored and separated by two conductors with different dielectric constants. The TCJY156M025R0090 is composed of a dielectric film of tantalum oxide, which is sandwiched between two layers of an electrically conductive polymer. The two outer layers act as the two conductors, while the dielectric layer stores the electric charges. Electric current crosses the dielectric layer through a phenomenon known as electrochemical migration, which is a process in which ions of the dielectric material are transferred across the capacitor. The current then flows back into the conductors through the process of electron diffusion.

When the capacitor is charged, the stored charges create an electric field between the two conductors. This electric field then serves to oppose the flow of current once the capacitor is discharged. As the electrons diffuse through the dielectric, the electric field and hence the capacitance of the capacitor decreases. The voltage rating of the capacitor is determined by the maximum allowed electric field strength based on the dielectric constant of the dielectric material and the thickness of the dielectric layer.

Conclusion:

TCJY156M025R0090 is a Tantalum-Polymer type capacitor that is used in a wide range of electronics applications, due to its high capacitance and low ESR. It is well known for its temperature compensation, high stability, and high frequency operation. The TCJY156M025R0090 works on the principle of storing and separating electric charges by two conductors with different dielectric constants and relies on the process of electrochemical migration and electron diffusion to cross the dielectric layer and flow back into the conductors.
