Tantalum capacitors, also called tantalum electrolytic capacitors, are a variant of electrolytic capacitors. They are polarized capacitors and typically consist of two conducting plates, a dielectric material, and an electrolyte. As they are polarized they typically have one negatively charged terminal and one positively charged terminal.

TH3C476M010C0800 is a type of tantalum capacitor, where the first three letters refer to the product line, “TH3” for example. The following two letters refer to the type of the capacitor, in this case refers to axial leaded tantalum molded case. The two numbers refer to the voltage rating and capacitance of the capacitor. The last two digits represent the tolerance of the capacitance from its nominal value in percentage (e.g. 10%).

Generally, the application field of TH3C476M010C0800 tantalum capacitors boil down to two main fields: they are widely used as output smoothing and decoupling capacitors in power supply circuits, or as input and output filters in high precision low noise analog circuits. Their working principle mainly relies on the ability of the capacitor to store charge in its dielectric material. This causes the capacitor to act as a separator between different nodes in the circuit, allowing alternating currents to pass while blocking direct currents.

Smoothing capacitors in power supply circuits are designed to reduce ripple current, or the alternating voltages between AC mains input and a DC output voltage. When the AC current flows through the winding of the power supply, the capacitor stores and releases power intermittently as the AC current pulses, giving the DC output a smooth waveform with fewer changes in voltage. The result is an improved voltage regulation in the DC supply.

Electrolytic capacitors are also used to filter the signals in analog circuits. In this application, the capacitors utilizes its charge-discharge properties to act as a low-pass filter. When a signal is passed through the capacitor, the voltage at either end of the capacitor changes by an amount proportional to the amount of charge passing through it. This enables the capacitor to block low frequency AC signals while passing on high frequency AC signals, resulting in a clean and distortion-free analog output.

TH3C476M010C0800 capacitors are also widely used as output smoothing and decoupling capacitors in power supply circuits due to their ability to minimize the amount of noise present in the output, as well as their relatively low impedance. This makes them an ideal choice when designing circuits that must operate in high noise environments, or when using high current circuits.

In conclusion, TH3C476M010C0800 tantalum capacitors are widely used in a variety of applications due to their excellent charge-discharge properties, low impedance, and high voltage capabilities. Their main applications are as smoothing capacitors in power supply circuits, and as input and output filters in high precision low noise analog circuits.
