Tantalum Capacitors TAJR474K020YNJ - application field and working principle

Tantalum capacitors are a type of electrolytic capacitor, a component of electronic circuits. The TAJR474K020YNJ capacitors use solid electrolyte, with good frequency characteristics and really low ESR. These capacitors are used in telecoms, power supplies and other high technology applications.

The TAJR474K020YNJ has a positive (+) aluminium cup and a negative (-) steel plate and is designed to be both small in size and good dissipate heat. The capacitance of TAJR474K020YNJ ranges from 4.7 to 100 µF, with a voltage rating of 2V to 16V, making it suitable for a variety of applications.

TAJR474K020YNJ capacitors have a working principle based on the usage of electrolyte materials, as any other electrolytic capacitors. They consists of an anode (positive) electrode, a negative anode, and a dielectric material. The dielectric material is a solid electrolyte, like aluminium oxides. When the capacitor is energised, a charge is stored on the anode, while an equal and opposite charge sets up on the cathode, attracting the electrons and creating an electric field.

The dielectric material separates the anode and cathode and works as an insulator so that no current can pass through the TAJR474K020YNJ. The dielectric material also helps to stop the flow of electrons from the anode to the cathode, increasing the capacitance of the capacitor and improving its reliability, stability and low self-discharge.

The TAJR474K020YNJ capacitor is characterized by its small size, high capacity, low equivalent series resistance (ESR), good high-frequency characteristics and good heat dissipation. It is also more resistant to vibration and shock than other types of electrolytic capacitors, allowing the capacitor to stand up to long-term operation in harsh environments.

TAJR474K020YNJ capacitors have a wide range of applications. They are used in power supplies, telecoms, medical and industrial equipment, wireless communication and automotive systems. In power supplies, they help stabilize the signal and reduce EMI. In telecoms, they provide signal filtering and signal stabilization. In medical and industrial equipment, they provide signal filtering, signal conditioning and signal stabilization.

Another common application of the TAJR474K020YNJ capacitor is in automobiles. It is used in the electrical system of the car to store and stabilize electrical energy, to help start the engine and to help the car maintain an optimal voltage level. It is also used for controlling the current in the circuits, providing protection against overheating, and providing protection against electrical shock.

In summary, TAJR474K020YNJ capacitors are versatile and reliable components used in a wide range of electronics and automotive applications. They are characterized by their small size, high capacity, low ESR and good heat dissipation. They are used in power supplies, telecoms, medical, industrial and automotive systems.
