Tantalum Capacitors

M39003/01-8263/HSD, commonly known as a tantalum capacitor, is an electrochemical capacitor. It is also one of the most common types of capacitors in the world. Today, tantalum capacitors are widely used in many electronic electrical systems and are available in various sizes and types. This article aims to explain the application fields and working principle of M39003/01-8263/HSD.

Application fields

Tantalum capacitors are used mostly in portable electronic devices, such as laptops, mobile phones, and other smaller electronic systems. The small size, low cost, and high capacitance of tantalum capacitors make them great choice for these applications. In addition, tantalum capacitors are also used in medical equipment, military communication systems, and satellite communication systems.

Tantalum capacitors can also be used to increase filtering performance in power supplies. By placing the capacitor in parallel with an inductor, it is possible to reduce the ripple of the voltage waveform produced by the power supply. This is useful in certain applications where a very stable voltage is required.

Working principle

A tantalum capacitor consists of two electrodes separated by a dielectric material. In the case of a tantalum capacitor, the electrodes are made from a tantalum material and the dielectric material is an oxide of the tantalum material. When a voltage is applied to the two electrodes, the dielectric material breaks down and a layer of oxide forms between the two electrodes.

When a voltage is applied, the oxide layer is formed and the two electrodes are able to store electric charge. The amount of charge that can be stored depends on the thickness of the oxide layer, which in turn depends on the voltage applied. The voltage applied to the dielectric material determines its capacitance, which is the measure of how much charge it can store.

When the voltage is released, the oxide layer breaks down and the stored charge is released. This process is known as “dielectric absorption” and it is one of the reasons why tantalum capacitors can be used in portable electronic devices. By taking advantage of dielectric absorption, it is possible to store and release a large amount of charge quickly, enabling the device to respond to user input.

Conclusion

M39003/01-8263/HSD is a common type of tantalum capacitor that is available in various sizes and types. It is mostly used in portable electronic devices, such as laptops, mobile phones, and medical equipment. The working principle of a tantalum capacitor is based on the formation of an oxide layer between two electrodes upon application of a voltage. This layer stores electric charge and its capacitance is determined by the voltage applied.
