Tantalum Capacitors

A tantalum capacitor is an electronic component of which the main function is to store energy in the form of electrical potential. It is primarily made up of tantalum and is also known as a Ta-Cap or a specifically-type capacitor. These unique types of capacitors are generally used in diverse types of electronic circuits, especially those involving high-frequency switching.The M39006/22-0133 is an example of a type of tantalum capacitor that is widely used today. This particular capacitance value can range from 10 pF to 220nF, with a maximum operating temperature of 125°C.

General Features and Applications

The general features that make this type of tantalum capacitor popular include its low ESR, small size, and higher temperature range. The value of ESR or equivalent series resistance is very low in these capacitors, meaning larger amounts of current can be drawn in shorter times using these capacitors. Additionally, they are extremely compact and lightweight, taking up plenty less space than other types of capacitors. Lastly, their high temperature range makes them usable in high-heat applications.

The M39006/22-0133 tantalum capacitor is used in a variety of applications. It is suitable for voltage supply filtering and smoothing in low to medium power circuit applications. It is also used as a storage device in high frequency applications like automotive DC/DC converters and is also used as part of a temperature sensing circuit for engine control modules.

Working Principle

Tantalum capacitors work on the principles of electrostatics, when an electric field builds up between two components. Generally, two thin plates are separated by a thin insulating layer, known as the dielectric. This dielectric material is made by combining a combination of oxide and material such as metal, ceramic, etc. Thus, when a voltage is applied across the plates, the dielectric is polarized, creating an electric field between the plates, which allows a current to flow through them. The capacitance value of the capacitor can be determined based on the size of the plates and the type of insulating material.

The M39006/22-0133 tantalum capacitor is a three-terminal device, with the two outer terminals being the plates, separated by a dielectric made from tantalum oxide. This oxide is also known as "surfactant" due to its ability to create a more consistent surface which leads to better charge retention, allowing the capacitor to store more energy. The third terminal is used to provide a voltage to the capacitor, which is necessary for the capacitance to work.

Other Types of Tantalum Capacitors

There are other types of tantalum capacitors such as the MnO2 type and the hybrid type. The MnO2 type has a dielectric made up of manganese dioxide, while the hybrid type has a dielectric combination of tantalum pentoxide and MnO2. Both of these capacitors are used in a variety of applications, from high frequency filtering to motor control.

Conclusion

The M39006/22-0133 tantalum capacitor is an important component of modern electronics, used for voltage supply filtering and smoothing, temperature sensing and high frequency switching. It works on the principles of electrostatics, with two plates being separated by a dielectric material, in this case, tantalum oxide. It is also lightweight and very compact, making it a good choice for various high density applications. There are other types of tantalum capacitors, like MnO2 and hybrid capacitors, with different dielectric materials, however, the M39006/22-0133 is the most popular choice.
