Tantalum Capacitors

The 572D106X0016P2T is a type of tantalum capacitors, which are widely used for a variety of purposes. In the electronic world, there are many types of capacitors with wide ranging specification and performance. They can be classified according to the dielectric material used in them, the stack structure and their operating conditions. By far, tantalum capacitors are the most popular in the capacitor category.

What are Tantalum Capacitors?

Tantalum capacitors are constructed by mechanically stacking polarised electrodes with tantalum granules impregnated with a dielectric of manganese dioxide that is sandwiched between two non-conductive end caps. They are represented by two pins with pins joined together by a metal plate or foil.

The capacitance of the device is the measure of the ratio of the voltage applied across it to the current flowing through it. Its capacitance value can range from a few pico-farads to several micro-farads, depending on its size and construction. The dielectric material used in the construction influences the maximum DC voltage that can be applied to the capacitor without causing it to fail.

Applications of Tantalum Capacitors

Tantalum capacitors are suitable for applications such as filter networks, noise reduction circuits, bypass capacitors, timing of signals, and many other circuits. Some applications requiring voltage in excess of the rated voltage limit for tantalum capacitors are often fitted with low-voltage ceramic capacitors in conjunction with tantalum capacitors.

The combination of tantalum capacitors and ceramics helps to reduce electrical noise and set the timing of signals in support of the data transmission rate.

In audio applications, the physical size constraints are the main attraction, coupled with high capacitive performance, low ESR and a two-terminal series capacitor, compared to other types of capacitors. This small form factor is especially desirable in consumer audio and portable systems, allowing manufacturers to reduce board size and save on costs.

Working Principle of Tantalum Capacitors

The working principle of tantalum capacitors is based on their construction, with their polarised electrodes separated by a dielectric, in this case manganese dioxide. When a voltage is applied across the capacitor, the current flows into the negative electrode and returns to the positive electrode as a phase shift in the current. In this way, electrical energy is stored and discharged at a later date as required.

Tantalum capacitors use two sets of plates comprised of two different metals, such as alumina and tantalum. These plates are typically covered with a layer of manganese dioxide dielectric material. When an electrical signal is applied, it creates an electrical field, which causes a charge to build up on one plate of the capacitor while the other plate remains neutral. This charge, or stored energy, is held until the applied voltage is changed or released and discharged by the capacitor.

Final Thoughts

The 572D106X0016P2T is one type of tantalum capacitor, with wide-ranging applications and great performance. As a common electronic component, it has many packaged form factors, an operating temperature range of -55 to +85 °C, and capacities up to 56µF. It is an ultra-stable, low-cost capacitor option for many applications.
