Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, a component of electronic circuits. It typically consists of a pellet of tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by a conductive material as a cathode. By applying a voltage to the two leads, positive on the anode and negative on the cathode, an electric field is created that causes a pool of ions to collect at the surface of the pellet. These ions form a very thin, dense layer of electric charge that gives the tantalum capacitor a very high degree of capacitance.

The TH3E106M050F0500 is a type of tantalum capacitor and is used in a variety of digital and analog applications. It has a capacitance of 106μF, a voltage rating of 50V, and a maximum DC ripple rating of 5000 mV.

Application Fields

The TH3E106M050F0500 is suitable for a variety of power-supply applications, including DC/DC converters, battery back-ups, and general analog and digital circuits. It can also be used in high-precision applications, such as clock oscillators, signal processing, and precision timing applications, due to its low ESR (equivalent series resistance) and high ripple current ratings.

Working Principle

The working principle behind tantalum capacitors is based on the electrochemical phenomenon of double layer capacitance. When a voltage is applied to the capacitor leads, the oxide layer (dielectric) is polarized and a charge equilibrium is formed between the oxide layer and the cathode. This charge equilibrium forms the basis for the capacitor\'s capacitance. Additionally, the capacitor also exhibits a certain amount of resistive and inductive characteristics due to the tangled structure of the anode pellet.

The TH3E106M050F0500 tantalum capacitor is a classic example of the working principle behind these capacitors. It has a maximum DC ripple rating of 5000 mV and a low ESR of less than 25 mOhms, making it ideal for applications where high-current, high-frequency performance is needed. Furthermore, its high surge current rating ensures that it will not be damaged by any instantaneous overvoltages.
