Tantalum Capacitors

The tantalum capacitor, also known as a Tantalum Electrolytic Capacitor, is an electrochemical device composed of two terminals and a solid, liquid, or gel electrolyte between them. This type of capacitor offers high capacitance values and is usually the smallest type of capacitor that can be produced. The use of tantalum capacitors has been increasing steadily over the years, and today, they represent a large portion of the capacitor market.

Tantalum capacitors are made using a ceramic form of tantalum (usually called ‘doped’ tantalum, because it has some elements added to it during its production process) and an electrolyte. The electrolyte is usually a gel, but sometimes a liquid, and it acts as a bridge between the two terminals of the capacitor. In operation, the tantalum metal layer absorbs the electrostatic charge from the electrolyte, which then acts to store the electrical charge in the capacitor.

173D475X9050X Application Field and Working Principle

The 173D475X9050X is a ceramic-based tantalum chip capacitor that is mainly used in applications that require high capacitance values. This type of tantalum capacitor is especially suited for use in power supply circuits, such as computers and consumer electronics. Due to its high dielectric constant, it is well suited for applications that require a low impedance and high current capability.

The working principle of the 173D475X9050X is relatively simple. When an electric current passes through the capacitor, a charge is stored in the ions of the electrolyte. This charge is then released upon a decrease in the electric current. The resulting release of the charge, in turn, produces a potential difference between the two terminals of the capacitor, thus providing an electrical energy storage mechanism.

The 173D475X9050X capacitor also has a low equivalent series resistance (ESR). This means that the current drawn from the capacitor upon charge-release is damped quickly, thereby reducing ripple voltages in the power supply circuit. This is an important advantage in applications in which ripple voltages need to be kept at a minimum for optimal performance.

In addition, the use of this type of capacitor also helps to minimize leakage current, as well as the possibility of damage to other components in the circuit due to overcharging. With its relatively small size, the tantalum capacitor is also a good choice for applications that require a low installation profile and a high dielectric strength.

Overall, tantalum capacitors offer many advantages to the circuit applications in which they are used. The 173D475X9050X capacitor, in particular, provides superior performance through its small size, low impedance, high capacitance, and excellent current capacity.
