TPSB476K010B0650

Tantalum Capacitors

The TPSB476K010B0650 is a type of tantalum capacitor. A tantalum capacitor is an electrolytic type capacitor composed of tantalum powder, vinyl polymer film and a metal electrode. It is polarized, which means its anode and cathode are distinct and must be connected properly to ensure it functions as intended. Understanding its fabrication, structure, application and features is important to using such types of capacitors.

Fabrication and Structure

The TPSB476K010B0650 has a maximum operating temperature of 125°C and a capacitance of 0.47μF. It is composed of tantalum powder, a solid electrolyte and two heat-sealed metal electrodes. The tantalum powder is pressed into a capsule and sintered, giving the capacitor a solid, compact cylindrical shape. The solid electrolyte consists of a mixture of aluminum oxide, barium oxide and chlorine ions that creates a semi-permeable barrier between the two metal electrodes. The electrodes are heat sealed to the sides of the electrolyte capsule.

Applications and Features

The TPSB476K010B0650 has several important applications. It is commonly used in circuit protection and filtering, for noise filtering and voltage stabilizing. Its wide temperature range and compact size makes it suitable for automotive applications. Its features include high capacitance performance, better ripple current ratings and a very wide temperature range. In addition, its unique construction makes it resistant to things like shocks, vibrations, and thermal cycling.

Working Principle

The working principle of a tantalum capacitor is based on electrostatic attraction and the electrical properties of a dielectric (insulating) material. When a voltage is applied to the metal electrodes, the positive charge accumulates on one and a negative charge accumulates on the other. This creates an electrical field between the two and creates a capacitance. This capacitance stores energy in the form of electric current, which can be discharged when needed.

Tantalum capacitors, such as the TPSB476K010B0650, are widely used because of their numerous practical applications and unique features. Understanding their fabrication and structure, as well as their working principle, is important for those looking to use such types of capacitors.
