Tantalum Capacitors

T491A105K025AT4513 is a type of tantalum capacitor, also known as a tantalum electrolytic capacitor. This type of capacitor uses tantalum metal for the anode and an electrolyte for the cathode. Capacitance is determined by the size of the anode\'s surface area and the dielectric constant of the electrolyte.

Applications Field

T491A105K025AT4513 tantalum capacitors are widely used in applications such as high frequency circuits, low-voltage circuits, and medium-power equipment, including but not limited to:

• Television sets
• Computers and peripherals
• Power supplies
• Switch and power electronics
• High-end and professional audio
• Instrumentation and aviation electronics

In addition to its wide range of applications, tantalum capacitors also offer a number of other advantages, such as low cost and high stability. These factors make them an attractive option for many electronics applications.

Working Principle

A capacitor is a device that stores energy in an electric field. Tantalum capacitors use an electrostatic charge to store this energy, creating an electrical field. The metal anode and the electrolyte act as an active path for conducting electricity, allowing for charge and discharge of the capacitor.

When the capacitor is connected to a voltage source, current passes through the electrolyte and the charge builds up on the anode until the capacitor is fully charged. When no current is passed through the capacitor, the capacitor slowly discharges until it has returned to zero charge.

Conclusion

T491A105K025AT4513 is a type of tantalum capacitor commonly used in many electronic applications. This type of capacitor uses tantalum metal for the anode and an electrolyte for the cathode, and is capable of storing an electrical charge. It is also highly stable and cost-effective, making it a very attractive option for many applications.
