Tantalum Capacitors

Tantalum capacitors, also referred to as tantalum electrolytic capacitors, are widely used in the electronics industry. They offer advantages in terms of size, high capacitance, temperature stability, and low equivalent series resistance (ESR). The T86E336K025EAAL is a type of tantalum capacitors. This article will discuss its application field and working principle.

Application Field

Tantalum capacitors are multi-purpose electrolytic capacitors, and they have a wide range of applications. They are used in many consumer electronics, such as televisions, computers, portable radios, and cellular phones. Additionally, tantalum capacitors are used in automotive applications, such as fuel injectors, exhaust gas recirculation, and power steering systems, due to their excellent operating performance at high temperatures. In addition, they are also used in industrial applications, such as motor drives and uninterruptable power supplies (UPS). The T86E336K025EAAL has a capacitance of 330 µF and a voltage rating of 25 V, making it suitable for general-purpose applications including audio circuits, power supply filters, and bypass/decoupling applications.

Working Principle

Tantalum capacitors are polarized devices, and the electrical connection between the two terminals requires electrons to flow in one direction only, depending on the charge given to the capacitor by the power source. The construction of the T86E336K025EAAL consists of a tantalum anode in the form of a pellet, which is wrapped in a thin layer of an electrolytic material such as manganese dioxide. This is then surrounded by a tantalum oxide layer that serves as the dielectric. The two electrodes are separated by a thin sheet of paper containing impregnated electrolyte. When a current is applied, electrons move from the positive terminal (anode) of the capacitor to the negative terminal (cathode) and an electric field is created across the dielectric, resulting in a charge being stored in the capacitor. When the current is removed, the stored charge is released, allowing the capacitor to act as a buffer.

Conclusion

The T86E336K025EAAL is a type of tantalum capacitor that can be used for general purpose applications due to its high capacitance and voltage rating. It has wide application fields in consumer electronic, automotive, and industrial applications. It functions by creating an electric field across the dielectric when a current is applied, thus allowing for the storage of charge. When the current is removed, the stored charge is released, allowing the capacitor to act as a buffer.
