Tantalum Capacitors

Tantalum capacitors are one of the most widely used types of capacitors. These capacitors are mainly used in telecommunications, medical equipment, consumer electronics, automotive electronics, and military/aerospace applications. A common type of tantalum capacitor is the T491A105K025AT4280.

Application Field

The T491A105K025AT4280 is a radial-leaded, solid-electrolyte non-polarized capacitor with a 2.5V DC rated voltage. Its main application fields are consumer electronics, automotive electronics, medical equipment, and military/aerospace electronics. It is used in switch-mode power supplies, voltage multipliers, energy storage applications, timing circuits, and many other applications.

Working Principle

The T491A105K025AT4280 is a type of electrolytic capacitor which is based on an electrolytic gel layer between two aluminum or tantalum plates. The plates are arranged in a cylindrical configuration which provides the capacitor with a good mechanical strength. Current passes through the capacitor when it is connected to a voltage source. The energy is stored in the electric field between the plates as a result of the movement of the electric charge.

The T491A105K025AT4280 has a low equivalent series resistance (ESR) that helps to prevent self-discharge by reducing the voltage drop when the capacitor is used in high current applications. The ESR also helps to increase the reliability and lifetime of the capacitor. Furthermore, these capacitors have a larger rated voltage than other types of aluminum electrolytic capacitors, making them suitable for applications with higher voltages.

Finally, the T491A105K025AT4280 has a high capacitance-to-volume ratio. This makes them ideal for high-density applications such as portable electronic devices. They are also more resistant to shock and vibration than other types of capacitors.
