Tantalum Capacitors

Tantalum capacitors are one of the most common type of capacitor used in a variety of applications. They are made up of a thin plate of tantalum metal and an electrolytic solution, which acts as a dielectric material. The tantalum plate is connected to two electrodes, one positive and one negative, and a dielectric material is placed between them. This dielectric material is then charged up and the capacitor stores electric energy.

Tantalum capacitors are generally used for high-frequency applications such as radio frequency circuits and for fast switching applications such as power supplies. They have very low equivalent series resistance (ESR) which means the current flowing through the capacitor is very low. This makes tantalum capacitors ideal for applications that require low power consumption.

Tantalum capacitors have a very long life span and can be used in a wide range of temperatures, from around -55°C to 125°C. They can handle large current flow and, compared to other types of capacitors, can withstand high voltages without any risk of destruction. This makes them an ideal choice for a variety of application, from safety critical systems to high frequency radio receivers.

The 199D225X0035B6B1E3 is one particular type of tantalum capacitor which is designed to offer higher current density and lower equivalent series resistance (ESR). It features a low ESR of 0.095mΩ per element and it offers the highest ripple current rating among this type of capacitor. It is also suitable for use in high temperature applications up to 125°C.

The working principle of a tantalum capacitor is based on the principle of non-polarity and the ability of the dielectric material to store and release electric energy. A thin sheet of tantalum is placed between two electrodes. When a voltage is applied, electric charges of opposite types accumulate at two different points on the plate, creating an electric field. This field causes ions to move from an electrode to another, thus creating an electric charge.

The charge stored in a tantalum capacitor is a function of the current density, frequency, temperature and the dielectric constant of the material used for dielectric. As the voltage increases, so does the amount of ions that are moved, thus increasing the charge stored in the capacitor.

Tantalum capacitors are widely used in a variety of applications due to their small size, high current density and low ESR. They can be used in circuits that transfer high frequency signals, in audio amplification or power supplies as well as in safety-critical systems where leakage current is controlled. The 199D225X0035B6B1E3 variant of tantalum capacitor is designed to offer higher current density and low ESR at higher temperatures, making it the perfect choice for a wide range of applications.
