Tantalum Capacitors

T491B155K025AS is a type of tantalum capacitor that is widely used in various electronic applications. It is designed to store energy and provide an electrical insulation between two conductors. A tantalum capacitor is a type of electrolytic capacitor that is made of tantalum and uses an electrolytic solution as the medium for storing an electric charge. It is similar to a standard electrolytic capacitor, but it has a much higher capacity and better electrical qualities.

Application Field

The T491B155K025AS is most commonly used in digital and analog circuits for applications such as filtering, decoupling and signal conditioning. It has a low ESR and a range of tolerance that makes it suitable for a vast range of electronics. It is widely used in the military and aerospace industry and has found applications in many consumer electronics such as mobile phones and computers.

Working Principle

The T491B155K025AS utilizes a technique of electrical storage in which an electrolysis solution acts as the medium to store electric charge. At one end, a thin layer of tantalum is used and it is held in a porous form in order to allow the electrolysis solution to penetrate. At the other end, a second layer of material is used to form a layer of insulation to prevent the charge from coming into contact with the anode material. This design allows the capacitor to store large amounts of electric charge for any given voltage and current requirement.

The capacitor works by creating an electric field between the anode and the cathode. As a voltage is applied across the capacitor, a current is produced which causes the electrolysis solution to start to move across the porous tantalum layer, creating an electric charge. As the electrolysis solution moves, the electric charge builds up, allowing the capacitor to store more energy than a standard electrolytic capacitor. Once the capacitor is fully charged, it can be discharged by either removing the voltage or the current.

The T491B155K025AS is a reliable and durable type of capacitor which is widely used in industrial, military and aerospace applications. It features a high capacitance and is capable of storing large amounts of energy for any voltage and current requirements. It is also a popular choice for consumer electronic applications due to its low ESR and range of tolerance.
