Tantalum Capacitors

T495X476K035ZTE200 tantalum capacitors are surface-mount electronic components which are used in a variety of applications. They are typically used as energy storage devices in DC-DC converters, pulse-generating circuits, regulator circuits, and signal filtering. The capacitors also possess an extremely long operating life, making them ideal for high volume and reliability critical applications.

Structure

Tantalum capacitors are composed of an anodic oxide film formed on the surface of a tantalum foil. The anode oxide layer acts as a dielectric material, which is then connected to two other external conductors in order to form a polarized capacitor. The external conductors are typically formed from a metal which is resistant to corrosion and oxidation, such as nickel, gold, or palladium.

Application Fields

T495X476K035ZTE200 tantalum capacitors are widely used in the automotive and aerospace industries due to their long-term reliability and high-temperature stability. They are also used for power-supply decoupling, filtering, and buffering in telecommunications, medical, and industrial electronics. Furthermore, their compact size makes them ideal for applications where board space is at a premium.

Working Principle

Tantalum capacitors work similarly to other capacitors by storing and releasing electrical charge. When a potential difference is applied across a tantalum capacitor, it stores the charge on a thin anodic oxide layer on the tantalum foil. When the potential difference is removed, the oxide layer releases the charge back into the circuit. The capacitance of a tantalum capacitor is determined by the thickness of its oxide layer and the area of contact between its electrodes.

Advantages

T495X476K035ZTE200 tantalum capacitors have a number of advantages over other capacitor types. They are very compact in size and have low equivalent series resistance (ESR) and low internal inductance, which make them suitable for high frequency and high power applications. Furthermore, they have an extremely long life cycle, often exceeding any other type of capacitor, making them ideal for use in applications that require reliability and long-term stability.
