Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a form of capacitors which uses a tantalum wire as its electrodes. These capacitors are used in a variety of applications from audio-video systems to consumer electronics due to their small size and higher efficiency compared to other types of capacitors. They are particularly advantageous for use in applications where packaging size and cost are the major considerations.

7-1879063-7 Application Field and Working Principle:

The 7-1879063-7 application field and working principle for a tantalum capacitor involve the use of a voltage-controlled layer of anode material, such as tantalum, which is interleaved with an electrolyte layer of ionizing salt. This the anode layer is then placed between two plates. A current applied to the plates results in the imposition of an electrical field (electric field) across the anode layer, making electrons flow from the anode material to the electrolyte layer. The resulting process is called electrolysis, and it is responsible for producing a capacitance effect in the capacitor which is measured in farads.

This capacitance effect is the result of the creation of positive and negative ions in the electrolyte layer. When the capacitor is supplied with voltage, the two plates attract the opposite charges, resulting in a temporary polarization of the conductor layers. The two plates are thus able to hold an electrically equivalent charge, this being an electric field which can be measured in terms of the capacitance of the capacitor.

In practice, a tantalum capacitor may consist of one or more layers of anodes, separated by an electrolyte layer of ionizing salt. A capacitor of this kind is commonly used in consumer electronics applications such as audio-video systems, due to its small size, higher efficiency than other types of capacitors, and low cost. Another advantage of the tantalum capacitor is its ability to perform at high temperatures, making it suitable for use in applications where temperatures are high or fluctuate.

In conclusion, the 7-1879063-7 application field and working principle of a tantalum capacitor involve the use of a layer of anode material and an electrolyte layer of ionizing salt to create an electric field in the capacitor. This capacitance effect is the result of the creation of positive and negative ions in the electrolyte layer, making it suitable for use in a wide range of consumer electronics applications due to its small size, higher efficiency, and ability to perform at high temperatures.
