Working Principle of T494D157K010AT

T494D157K010AT tantalum capacitors use a dielectric material made from a tantalum pentoxide (Ta2O5) and an anode made from a sintered pellet of pure tantalum. The anode is then coated with a conductive material, such as an organic or polymer-based material, to provide the necessary electrical connection to a circuit. The cathode is usually made from a manganese dioxide based electrolyte, with a voltage rating ranging from 4V to 50V. When connected to a voltage source, the anode and cathode act as oppositely charged capacitors, storing and releasing electrical energy when the voltage changes.The dielectric material of the Ta2O5, is able to store a large amount of electrical energy and has excellent characteristics, such as good temperature stability, high dielectric strength, and high insulation resistance. This makes the tantalum capacitors ideal for applications where small size, high temperature range, and long lifetime are critical.The T494D157K010AT capacitor has a capacitance range of 10 to 160nF and an operating temperature range of -55 to 85C. This allows them to be used in applications where extreme temperatures are encountered. Additionally, the tantalum capacitor offers a long service life of up to 1,000,000 hours, making it suitable for applications where long-term reliability and stability are essential.
