Tantalum Capacitors

Tantalum capacitors are special capacitors made from tantalum, which is a metal rare explored from the land. This special kind of capacitor is usually applied in various applications. The M39003/01-2837/HSD is a catalog of the popular type of tantalum capacitors, including values ranging from 363 to 1835.

Application Field

One of the most popular application fields for tantalum capacitors is filtering and storage of smooth DC voltage in digital circuit. As a kind of stable storage component, it can provide a constant and stable flow of power and prevent flickering and breakdown in systems. Moreover, with its high-energy density and compact size, it is also suitable for high-power and miniaturized applications.

In addition,by using an ultra-low equivalent series resistance (ESR) tantalum capacitor, the power supply circuit is controlled, the rise time, the quiescent point and ripple of the power supply circuit. It is also frequently used to filter radiating and various noises in the current AC circuit. Moreover, since it can provide more stable output voltage, the signal transmission of audio equipment in high frequency circuit is also improved.

Working Principle

When the terminals of the tantalum capacitor are connected to the positive and negative poles of the power supply, there will be an electric field formed between the anode and the cathode, and the electricity leakage is extremely small. The structure of the tantalum capacitor is composed of electrolyte and metal oxide layer inside, and the working principle lies in that when there is a voltage difference between the capacitance of the two electrodes, the electrolyte ions will be attracted to the anode side, forming an electric double layer at the interface between the metal oxide layer and the anode.

At the same time, the electrons on the anode side will move to the electrolyte side, so that the internal charge of the electrodes of the two sides is equal, and the actual capacitance is formed through the surface of the oxide film. So that when a current is applied, the anode side will be charged first, and after a certain pressure, the oxide film layer will break through, and the current will flow in series, so that with the increase of the electricity, the capacitance of the capacitor will increase and reduce.
