Tantalum - Polymer Capacitors

T540D477M004DH87107610 is an example of a type of capacitor commonly referred to as a tantalum polymer capacitors. Tantalum capacitors are electrochemical capacitors that use a tantalum oxide (Ta2O5) dielectric material which is a greatly stable material.

Application Field

Tantalum polymer capacitors are widely used in various electronic devices. They are often used in applications where size restrictions or high ripple current is required. Many consumer electronics, such as computers, smartphones, tablets, and audio systems contain such capacitors to store and release pulses of electricity when needed. Industrial applications include power supplies, electric motors, robotics and other automation systems.

Working Principle

The working principle of tantalum polymer capacitors is based on the electrochemical charging of the tantalum electrode. The tantalum is immersed in a liquid electrolyte, which provides the necessary ions to form a stable oxide film on the material\'s surface. This oxide layer acts as a dielectric — an insulating material that allows electric charge to pass through it freely. When electric current passes through the oxide layer, electric charges accumulate on its surface and create a capacitance. The electric charge is stored in the oxide dielectric until the capacitor is discharged. This accumulation and release of electric charges is the basic principle of a capacitor.

Advantages

Tantalum polymer capacitors are not only small and lightweight, but also have a long life expectancy and a very low cost. They also provide high capacitance values and an excellent frequency response. Furthermore, they are very reliable and can maintain a steady capacitance over a wide temperature range. They are also resistant to extreme temperatures, humidity and vibration.

Conclusion

T540D477M004DH87107610 is an example of a tantalum polymer capacitor, a type of capacitor used in a wide variety of electronics and automation applications. These capacitors are reliable and efficient, and offer a long life expectancy as well as a low cost. They also offer high capacitance values and a wide temperature range, making them an ideal choice for many applications.
