Tantalum Capacitors

173D334X0035U application field and working principle

Tantalum capacitors are a type of electrolytic capacitors. These capacitors are relatively small, but have an excellent power-to-size ratio. They are also more reliable than many other types of electrolytic capacitors and are used in the majority of electronic devices. Tantalum capacitors are usually found in electronic circuits for the purpose of stabilizing or increasing the available internal power. The most common tantalum capacitor consists of a tantalum powder or pellet core with two electrodes attached, one on each side of the core.

The 173D334X0035U is a type of tantalum capacitor and is typically used for filtering, bypassing and decoupling applications. It is designed to provide high capacitance values in a small package, hence it is often used as an alternative to SMD aluminium electrolytic capacitors. These kinds of capacitors are rated up to 16V and have a capacitance ranging from 1µF to 22µF.

How It Works

Tantalum capacitors work on the same principle as other electrolytic capacitors, being able to store energy electrostatically in an electric field. The core of the capacitor is made of tantalum powder, which is molded into a disc or pellet and then sintered under pressure to create a stable solid. A layer of dielectric oxide is then grown around the tantalum pellet and two anodes, often made of silver, are attached. The anodes are then electrically connected to a capacitor\'s external leads. When an electric field is applied, an electrochemical reaction takes place which creates an electrical potential difference on each side of the capacitor\'s body, thus creating a closed electrical circuit.

Tantalum capacitors also benefit from their tight tolerance, which is usually ±20%. This tolerance is greater than that of other capacitors, and it is usually even higher if any special requirements are needed. The tantalum capacitors also provide excellent long-term stability and reliability. The capacitance value of a tantalum capacitor rarely changes and it is much more resistant to the effects of aging, temperature, and humidity.

Applications

Due to their small size and high capacitance values, 173D334X0035U capacitors are used in a variety of applications. They are commonly used in applications such as power-line filtering, as they are able to eliminate any noise caused by EMI. They are also used as a decoupling capacitor, which helps reduce the voltage ripple in power supplies, and as a bypass capacitor to provide current for high-frequency signals.

The 173D334X0035U tantalum capacitor is also commonly used in circuit protection, as it is able to provide low impedance at high frequency, and it can also shunt high-frequency interference away from the components. Tantalum capacitors are also used in switch-mode power supplies, digital signal processing, and motor-control circuits.

Conclusion

Tantalum capacitors, such as the 173D334X0035U, are an important part of the modern circuitry and provide great performance, reliable stability, and a high power-to-size ratio. For these reasons, they are often used as alternatives to other capacitors in the majority of electronic devices, and find use in applications such as power-line filtering, decoupling, bypassing, and circuit protection.
