Tantalum Capacitors

T86D226K025EASL Application Field and Working Principle

Tantalum capacitors are polarized electrolytic capacitors that are widely used in both consumer and industrial electrical and electronic circuits. The most popular type of Tantalum capacitor is the T86D226K025EASL model, which is characterized by a small size, low leakage current, and high capacitance. In this article, we will discuss the application field and working principle of T86D226K025EASL tantalum capacitors.T86D226K025EASL tantalum capacitors have a wide range of applications. They are used in integrated circuit (IC) packaging, audio amplifiers, switching power supplies, and even high frequency electronic equipment. They are also used in a wide range of analog circuits and as stabilizers for digital circuits. They can also be used to reduce power dissipation in battery-powered circuits since their leakage current is very low.A tantalum capacitor works by utilizing a three-layer structure. The outer two layers are dielectrics made of tantalum pentoxide, while the inner oxide layer acts as an insulator. An electrolyte solution is placed between the dielectrics, and electric current flows between the two dielectrics. The size of the capacitor is determined by both the size of the dielectrics and the distance between them.The ability of tantalum capacitors to store electrical charges is the result of a phenomenon known as "charge balancing”. This means that anytime an electric current flows through a capacitor, an equal amount of opposite charge is also stored. As a result, a charge imbalance is established, creating an electric field between the two layers of the capacitor.When a voltage is applied to the terminals of a tantalum capacitor, the electric field causes ions in the electrolyte to move, creating a current. This current is what allows the capacitor to store electric charges. When the voltage is removed from the capacitor, the electric charges stored upon its release are transferred back to the capacitor, so it can store charges again. This process continues as long as electric current is applied to the capacitor.In conclusion, T86D226K025EASL tantalum capacitors are widely used due to their small size and low leakage current. They are most commonly used in IC packaging, audio amplifiers, switching power supplies, analog circuits, and digital circuits. The working principle of a tantalum capacitor is to create and maintain a charge balance, in which an electric field is established between two layers of the capacitor and the ions in the electrolyte are allowed to move when an electric current is applied.
