Tantalum capacitors are advanced passive electronic components, which belong to a class of capacitors known as electrolytic capacitors. They are usually composed of tantalum metal as the anode and a porous oxide layer as the dielectric. They find extensive use in many applications such as cellular phone, digital cameras, computers, and laptops.

The T350A105M025AT is a particularly popular tantalum capacitor. It has a total capacitance of 105µF, a rated voltage of 35 VDC and an ESR rating of 25 milliohms. This type of capacitor is typically used in power supply decoupling, coupling, filtering and timing applications.

Working Principle

The T350A105M025AT tantalum capacitor operates on first principles of capacitance. Capacitance is the ability of a device to store electrical charge and is measured in farads (F). A capacitor consists of two conductive plates separated by an insulating material known as the dielectric. When a voltage is applied between the plates, an electric field is created in the dielectric, which enables the capacitor to store charge. The amount of charge stored is proportional to the size of the capacitor, hence bigger capacitors store more charge than smaller ones.

The T350A105M025AT uses a tantalum-oxide dielectric, which gives it higher capacitance than other types of capacitors. The high dielectric constant of tantalum oxide means that the capacitor can store more electrical charge. The higher the voltage applied, the more charge the capacitor can store. The capacitance of the capacitor however, is limited by the area of the plates, the distance between them and the dielectric permittivity of the material used.

Application Field

The T350A105M025AT is used in a range of applications in consumer electronics, such as smart phones, cameras, and computers. It is used for power supply decoupling, meaning that any fluctuations in the voltage of a power supply are filtered out, ensuring the components connected to the supply receive the correct amount of voltage at any given time.

It is also used for coupling, which requires transferring the signals from one circuit to another. This capacitors facilitate this process in various devices as it is able to block the direct current signals and let through the alternating radio signals.

It also finds use in timing applications such as in clocks and timers. The capacitor can store charge and then release it slowly according to the user-specified rate to activate the connected device.

The T350A105M025AT is also used in audio equipment such as amplifiers and speakers, which require the capacitor to filter out any distortions or noise.

It is also used in high-end medical equipment, such as MRI and CT scans, where the device requires a high level of filtering for proper functioning.

Conclusion

The T350A105M025AT is a popular tantalum capacitor which finds use in a variety of applications, ranging from consumer electronics to medical equipment. Its high capacitance and rated voltage make it suitable for high-end applications and its ESR rating ensures it provides dependable performance. It operates on basic principles of capacitance and its dielectric material ensures an efficient charge storage capability.
