Tantalum Capacitors

Tantalum capacitors are among the most commonly used capacitors due to their high capacitance, high frequency, and long service life. The T502D106K025AG61107280 capacitor is one of many in the tantalum family.

Application Field

Tantalum capacitors, such as the T502D106K025AG61107280, are popular for their ability to hold a charge. This characteristic allows capacitors to be used in numerous types of electronic circuits, such as in voltage regulation, signal filtering, and bypassing. Essentially, the primary function of a capacitor is to block direct current while allowing alternating current to pass through. In addition to their blockage of current, tantalum capacitors are also popular due to their ability to store electrical charge.

These smaller capacitors are usually used for lower-voltage, low-current applications. Examples of these applications include microphone preamps, clock timing, radio receivers, and other types of digital circuitry. Larger capacitors can be used for audio power amplifiers, power filtering, and other similar high-current applications.

Tantalum capacitors are also used in many PC motherboards, as well as in camera systems, LED lighting, and power supplies. In power supplies, they play an important role in the fact that they can hold a current even when the main system is turned off.

Working Principle

The T502D106K025AG61107280 capacitor is composed of two tantalum metal plates (anode and cathode) interspersed with interleaving layers. The interleaving layers typically consist of oxide or nitride insulation. The plate sandwiched between the anode and cathode is known as the dielectric layer.

The capacitance created by the Tantalum capacitor is a function of the area of the two plates, the distance between them, and the type of dielectric material used. This capacitance stores electrical energy in the form of electric potential. This electrical energy can be used to supply current for a variety of applications.

The higher the voltage applied across the capacitor plates, the larger the capacitance created by the capacitor. As a result, when the capacitor is in a low voltage situation, the capacitive reactance is high, and when the voltage rises, the capacitance decreases. Therefore, different voltage applications will require different capacitance values.

When a current flows through the capacitor plates, a small amount of instantaneous charge is stored on each plate, which creates a short circuit. This short circuit can cause the capacitor to fail. In order to protect the capacitor from this short-circuiting, tantalum capacitors may be coated with a protective lacquer.

Conclusion

Overall, the T502D106K025AG61107280 capacitor is one type of the many Tantalum capacitors available. These capacitors have gained worldwide popularity for their ability to hold a charge and provide current for a variety of electronic applications. Additionally, the capacitors work on the principle of the capacitance created by the two metal plates interspersed with the dielectric layer. Such capacitors are frequently used in PC motherboards, camera systems, and LED lighting.
