T491D476K020AT7280 is a type of tantalum capacitor. It is an excellent component for design and installation in both low and high-temperature environments. Tantalum capacitors are “non-polarized” capacitors that are sometimes referred to as solid electrolytic capacitors. The significant difference between a tantalum capacitor and a standard electrolytic capacitor is the dielectric material used. For example, a typical aluminum electrolytic capacitor may use an electrolytic as the dielectric, while a tantalum capacitor will use a tantalum pentoxide powder.

The application field of T491D476K020AT7280 is wide. It can be used in a variety of electronics equipment such as computers, mobile phones, audio amplifiers, and industrial control systems, etc. It is also used in power electronic circuits, such as switching circuits, rectifying circuits, switching power supplies, and many other applications. The performance of T491D476K020AT7280 can maintain its level even in extreme environments, and its temperature range is -55°C to +125°C. Moreover, it can adjust temperature compensation, suitable for a wide range of temperature environments.

The working principle of T491D476K020AT7280 is based on electrochemical double-layer capacitor technology, commonly known as EDLC. The EDLC uses a porous metallic electrode and a carbon electrode to form a double layer. During operation, a voltage applied between the two electrodes will cause two opposite charge accumulate in the two layers, with one side carrying a positive charge and the other side a negative one. This voltage creates a capacitive storage element without any chemical interaction between the two electrodes.

An EDLC consists of an electrolyte, an anode (working) electrode, and a cathode (counter electrode). An electric current is passed through the electrolyte and the anode, which causes an electrolytic reaction on the anode, resulting in an electric field across the capacitor. This electric field causes electrons to travel across the capacitor, creating an electrostatic field which stores energy. The capacitor then slowly releases this energy until it is completely discharged.

T491D476K020AT7280 has high capacitance and low resistance so that it can handle more transient currents and working at higher temperatures than other types of capacitors. It has a long life span and is also resistant to high operating temperatures and vibration. In addition, it is also a good choice for noise reduction in electronics circuits. The capacitance of this type of capacitor can be from a few hundred pF to several hundred thousand pF, and it can be used in surface mounting, leaded mounting, or hybrid leaded packaging.

T491D476K020AT7280 can provide great performance and long-term stability of the capacitance value even in extreme conditions. Moreover, its performance can remain stable in a wide temperature range with excellent high frequency characteristics and low ESR making it a perfect choice for many applications.
