Tantalum Capacitors

T491B225M035AT4280 can be classified as a type of tantalum capacitor. Tantalum capacitors are components used in various types of circuits and applications, offering a level of reliability that cannot be replicated with standard electrolytic capacitors. Some of their most common uses include applications as diverse as cellular telephones and computer electronics.

What is a tantalum capacitor?

A tantalum capacitor is an electronic component that uses the chemical element tantalum to store electrical charge. It is made from an electrolytic conductor, such as liquid electrolyte, that is usually enclosed in a dielectric material. This is then used to create a “sandwich” of alternating layers of tantalum oxide, electrolyte, and tantalum metal. This structure ensures that when a voltage is applied, the stored charge is proportional to the magnitude of the applied voltage.

Application field for T491B225M035AT4280:

T491B225M035AT4280 is ideal for applications that require a high quality, low leakage capacitor with a long service life. It is an excellent choice for applications like automotive electronics, communications and medical equipment, industrial and commercial power supplies, avionics and telecommunications equipment, or any application where the reliable delivery of energy is critical. The capacitor\'s unique construction and wide capacitance range allow it to operate effectively in conditions ranging from -55°C to +105°C.

Working Principle

T491B225M035AT4280 suppresses alternating currents and stores energy similar to a battery. When subjected to a voltage, the capacitor will charge up until the amount of potential electrons seeking to enter the capacitor are equal to the amount exiting. This is known as the Faraday constant, due to its high charge storage capability. When a voltage is applied to a tantalum capacitor, it stores a predetermined amount of energy, which is then released when the voltage is decreased. In other words, the capacitor acts like a rechargeable battery, storing energy when the voltage increases and liberating it when it decreases.

Conclusion:

T491B225M035AT4280 is a type of tantalum capacitor, specially designed for reliable and consistent performance in applications where a long service life is critical. It is suitable for applications based on its highly reliable low leakage technology and wide capacitance range. It also is designed to handle environmentals as harsh as -55°C to +105°C.
