Tantalum capacitors are primarily used in applications such as decoupling and filtering, as well as in high frequency, high current, and high temperature circuits. The TAJS224M035RNJ is an example of a tantalum capacitor that is designed for demanding applications and offers numerous advantages, including low-ESR, high ripple current capability and voltage rating, low leakage current, and low impedance. The TAJS224M035RNJ is a very popular part with a wide range of applications and the following article explains its working principle and application field.

The TAJS224M035RNJ capacitor employs an anode of solid tantalum metal that is sintered with tantalum oxide. These parts also incorporate a baffle in the anode to increase the volumetric efficiency of the part, as well as a dielectric layer made out of manganese dioxide. These parts are wrapped in a non-conductive epoxy-encapsulated case, which adds physical protection and provides a means for mounting the capacitor. The electrolyte incorporated into the part is an organic solvent-based electrolyte.

The working principle of a tantalum capacitor is similar to that of an aluminum electrolytic capacitor. It functions as a dielectric material between two conductors – an anode and a cathode. When a source of electric potential, such as a battery or a power supply, is connected to the capacitor, it charges to the potential applied. The charge stored on the anode plate of the capacitor is equal to the total charge stored on the capacitor divided by the area of the anode plate. The charge stored on the capacitor is proportional to the voltage applied to the capacitor, and the capacitance of the capacitor is determined by the size of the anode plate and the dielectric constant of the tantalum oxide.

The TAJS224M035RNJ is a SMD tantalum capacitor that offers an excellent combination of high ripple current capability and low ESR. It features a capacitance of 2.2μF and a voltage rating of 35V. Due to its low ESR rating, it is a suitable choice for decoupling applications and for providing a low-impedance power source to low-power logic circuitry.

The TAJS224M035RNJ is also well-suited for applications requiring high frequency operation, such as RF circuits and switching power supplies. These SMD tantalum capacitors are suitable for automotive, computer, and consumer electronics applications as well as for industrial, energy, and medical equipment. Their robust construction and low ESR also make them ideal for battery-backed memory devices and other applications that require a reliable power source.

In summary, the TAJS224M035RNJ capacitors have been designed for demanding applications, such as RF and switching power supplies, with their low ESR and high temperature ratings. They offer the advantages of high ripple current capability and low impedance. Because of their robust construction and low ESR, they are suitable for automotive, computer, consumer electronics, industrial, energy, and medical applications. The working principle of a tantalum capacitor is similar to that of an aluminum electrolytic capacitor; it functions as a dielectric material between two conductors, an anode and a cathode. When an electric potential is applied, the capacitor charges to the potential and the total charge stored is proportional to the voltage applied.
