T491D476K020AH

T491D476K020AH is one of the Tantalum capacitors. It is a type of electrolytic capacitor, which utilizes a Tantalum element as the anode. This type of capacitor is known for its high volumetric efficiency, wide range of temperature and voltage ratings and extended operating life.

In the context of electronics, capacitors are electrical components that store electrical energy in an electric field. It essentially acts like a battery, but instead of storing chemical energy, it stores electrical energy. A standard capacitor generally consists of two metal plates separated by an insulator - the dielectric.

In a Tantalum capacitor, the anode is made of the element Tantalum, which is very resistant to oxidation and can retain its electrical properties at high temperatures. The Tantalum element is also able to hold a large amount of charge, which gives the capacitor its large capacity.

The T491D476K020AH Tantalum capacitor has a voltage rating of 4.7 Volts with a temperature rating of -55°C to +125°C. It has a capacitance value of 470µF, which means it can store up to 470µF of charge. The capacitor also has a high ripple current rating of 1100mA. Its extended operating life of 2,000 hours also makes it suitable for long-term applications.

Given its high capacity, large voltage rating, high ripple current and extended operating life, the T491D476K020AH Tantalum capacitor is suitable for a variety of applications, including low-voltage DC power supplies, radio tuning circuits, and high-frequency pulse circuits. In addition, the capacitor’s large capacitance also makes it suitable for decoupling applications, where it can help reduce electromagnetic interference.

When a voltage is applied to the capacitor, the electric field created by the charge separation induces an electric current, which quickly charges the capacitor to its rated voltage. The capacitor then acts as a store of electric energy until it is discharged, which is usually when the circuit is turned off.

T491D476K020AH Tantalum capacitors are widely used in a wide range of applications and can provide reliable performance and extended operating life. They are ideal for low-voltage DC power supplies, radio tuning circuits and high-frequency pulse circuits, as well as decoupling applications. The capacitor’s high volumetric efficiency and wide temperature and voltage ratings further add to its reliability and suitability in these applications.
