T495D476K020ATE100

T495D476K020ATE100 is a type of tantalum capacitors, which is made up of tantalum, an element with a symbol of Ta and atomic number of 73. A tantalum capacitor is an electrochemical capacitor with a tantalum metal as an electrode, which has a larger and more stable capacitance value than any other type of capacitor. The most common types of tantalum production are molded tantalum, dipped tantalum, foil type tantalum and sintered tantalum.

Application Field

The T495D476K020ATE100 capacitor is designed for high-performance applications requiring a combination of small-size, high-frequency, and wide temperature range capability. It is suitable for use in mobile radio, digital television, personal computers, digital cameras, printers, and electronic application instruments. It is also suitable for high-reliability applications in automotive, medical, and industrial fields.

Working Principle

Tantalum capacitors work on the principle of electrochemical capacitance, which is the ability to store energy in an electric field between two metal electrodes. The electric field created between the electrodes sustains charge and power over time, much like a rechargeable battery. The metal electrode acts as a capacitor dielectric, while the electrolyte acts as another dielectric material. In the T495D476K020ATE100 capacitor, the metal electrodes are made of tantalum, while the electrolyte is composed of theta-butylferrate (TBF) manganese dioxide.

The working principle of the T495D476K020ATE100 capacitor relies on the formation of a double layer electrochemical capacitor. This causes an increase in the capacitance through an increase in the surface area of contact between the electrodes and the electrolyte. When a voltage is applied, a positive charge is built up on one of the electrodes, while a negative charge is built up on the other electrode. This creates a polarized electric field across the capacitor, which then stores electrical energy.

The T495D476K020ATE100 capacitor offer a number of advantages over other types of capacitors. It has a high capacitance-to-volume ratio, excellent mechanical and thermal stability, long shelf life, high reliability and relatively low cost. These features make it an ideal choice for a wide range of high-performance electronics and high-reliability applications.
