Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor distinguished by their use of tantalum as an anode, and thus their characteristic construction and performance. Long used in consumer electronics, modern capacitors of this type find use in a range of industrial and military applications. Understanding the working principle of a tantalum capacitor, as well as those areas in which it is beneficial, is essential for designers and engineers wishing to select the right component for a specific application.

The Construction and Operation of a Tantalum Capacitor

The basic construction of a tantalum capacitor is similar to all other electrolytic capacitors. It features two metal plates or ‘electrodes’ separated by an insulating material called a ‘dielectric’. The first electrode consists of a loop of tantalum or tantalum alloy that serves as a anode. This is then coated with a thin insulating layer of oxide and then made porous by etching. The dielectric and second electrode, known as the ‘ cathode’ are then layered over the oxide-coated tantalum. The cathode consists of manganese dioxide, a layered oxide containing both manganese and oxygen. It is connected to the outer casing of the capacitor, which is used as an electrical contact to the outside circuit.When the capacitor is connected to a power source, an electric field is created between the two electrodes. This electric field creates an oxide layer on the surface of the tantalum anode, increasing its surface area. This oxide layer is then able to store large amounts of electric charge between the anode and cathode.

Benefits of a Tantalum Capacitor

Tantalum capacitors possess several advantages over other types of electrolytic capacitors. Firstly, they have lower equivalent series resistance (ESR) than aluminium electrolytics, meaning that tantalum capacitors can help to reduce the amount of heat generated in the circuit. This can make them extremely attractive for use in high-temperature circuits, as well as those that are highly impedance-sensitive.They are also around 30% smaller than aluminium capacitors of the same capacitance, making them ideal for compact and confined circuit designs. Any miniaturised components used around the capacitor can also reduce the stress on the components overall, as well as aiding in heat transfer.Despite their small size, tantalum capacitors also have excellent stability and reliability when used in extreme temperature conditions, offering a wide operating range and improved frequency response when compared to other types of capacitor. This makes them suitable for a range of industrial and military applications, such as automotive and aerospace industry, as well as consumer electronics.

The Application Field and Working Principle of a 199D156X0016C6B1E3 Tantalum Capacitor

The 199D156X0016C6B1E3 is a miniature tantalum capacitor that is designed for use in a range of consumer applications, such as audio/video signals, military equipment and automotive systems.This capacitor has a nominal capacitance rating of 124uF and a voltage rating of 16V, making it well-suited to a range of automotive and other specialized circuits. Its small size and high capacitance to volume ratio make it ideal for applications requiring a high capacitance in a limited space.The working principle of this capacitor is similar to all other types of tantalum capacitors. A thin layer of oxide is formed on the surface of the tantalum anode when it is connected to the power source, increasing its surface area. The oxide layer is then able to store large amounts of electric charge between the anode and the cathode, which is made of manganese dioxide. This type of capacitor offers superior temperature and frequency response when compared to other types of capacitor, making it suitable for a variety of industrial and military applications.
