Tantalum Capacitors

Tantalum capacitors are a type of electronic component that use tantalum metal in their construction. They are widely used in a variety of electronic equipment, including military and aviation applications, as well as consumer electronics and medical applications. The capacitance range of tantalum capacitors ranges from 0.01uF to 1000uF, and they come in polarized, non-polarized, and many other forms.The 13008-012KESZ application field and working principle of tantalum capacitors can be divided into two types: electrolytic and solid tantalum capacitors.

Electrolytic Tantalum Capacitor

Electrolytic tantalum capacitors are one of the most commonly used tantalum capacitors. They are an electrolytic capacitor with tantalum powder or tantalum salt sandwiched between two aluminum (or manganese dioxide, in some cases) electrodes. This type of capacitor has the advantage of having a large capacitance for a given volume—typically up to 1000uF in a small package. They also have a relatively low voltage rating, typically up to 36V, meaning that they are restricted to lower-power applications.The working principle of an electrolytic tantalum capacitor is based on the electrolyte, usually a solution or a paste of aluminum chloride, which is sandwiched between two layers of a tantalum-oxide film. This electrolyte allows the transfer of charge between the two electrodes, thereby acting as a dielectric. When voltage is applied to the capacitor, ions flow through the electrolyte and form a deposited layer on each electrode. This charge is then stored in the capacitor and can be discharged when needed.

Solid Tantalum Capacitor

Solid tantalum capacitors, unlike electrolytic tantalum capacitors, do not contain any electrolyte. Instead, the two electrodes are separated by a surface layer of oxide. This layer of oxide acts as the dielectric which allows the capacitor to store charge. The solid tantalum capacitor is formed by sputtering metal onto a base material, which can be either tantalum or niobium oxide. The working principle of a solid tantalum capacitor is based on the surface layer of oxide, which is very thin and permeable to charge. When voltage is applied to the capacitor, electrons flow through the oxide layer and accumulate in the capacitor until the voltage drops below the maximum limit. The accumulated charge stays in the capacitor until it is discharged when a current is passed through the capacitor.Compared to electrolytic tantalum capacitors, solid tantalum capacitors have higher capacitances, larger voltage ratings, and better temperature stability. Solid tantalum capacitors typically have a capacitance range of 0.1uF to 10uF and can withstand voltages up to 25V.

Conclusion

The 13008-012KESZ application field and working principle of tantalum capacitors are very important for a wide range of electronic applications. The two main types of tantalum capacitors are electrolytic and solid, and each has its own advantages and disadvantages and the best choice depends on the specific application. Electrolytic tantalum capacitors have the advantage of having a large capacitance for a given volume but have a relatively low voltage rating. Solid tantalum capacitors, on the other hand, have a higher voltage rating and higher temperature stability but have a lower capacitance range.
