Tantalum Capacitors

Tantalum capacitors, such as the T95Y685K025EZSL, are a type of electrolytic capacitor that consists of a metal layer of tantalum between two electrolytic layers. This type of capacitor is higher capacitance than ceramic or film capacitors, and it is also more stable and reliable than other electrolytic capacitors. It is used in a wide range of electronic applications, including audio equipment, power supplies, computers, transmitters/ receivers, industrial controls, and USB interfaces.

Application Field

The T95Y685K025EZSL is a surface mount tantalum capacitors that can provide a capacitance range of 0.15 µF up to 4.7 µF. This type of capacitor is mostly used for bypassing, filtering, energy storage, and DC blocking applications. It is particularly suitable for military, medical, and industrial applications due to its high reliability and performance stability. It can also be used in applications where space is at a premium, such as cell phones, televisions, and other small devices where normal electrolytic capacitors cannot fit.

Working Principle

The tantalum capacitor is essentially an electrolytic capacitor with a dielectric layer of tantalum between two electrodes. As with most electrolytic capacitors, the tantalum capacitor uses a porous oxide solution as the electrolytic layer. The difference between a tantalum capacitor and other types is the dielectric material. Instead of the normal solid dielectric layer of another type of capacitor, the electrolyte occurs in a thin film of oxide that forms on the surface of the tantalum. This thin oxide layer creates a higher electrical capacity than other types of capacitors. The capacity of a tantalum capacitor is proportional to its size and thickness, so a smaller size will generally result in a smaller capacity. The higher capacity of a tantalum capacitor also results in a higher leakage current than other types of capacitors.

Advantages of Tantalum Capacitor

Tantalum capacitors offer a number of advantages over other types of capacitors. They have a high operating temperature range, low coil inductance, and a wide range of capacitance values. Additionally, they are highly reliable, with almost no possibility of failure due to their robust construction. They are also highly resistant to mechanical shock and vibration, making them useful in a variety of industrial applications. Finally, they are relatively inexpensive compared to other types of capacitors, making them ideal for use in low-cost designs.
