Tantalum Capacitors

Tantalum capacitors are small and versatile electronic components made from the metallic element tantalum, used primarily in the electrical industry. The components are used for coupling, decoupling, and bypassing signals, as well as for providing energy storage. The name “tantalum” is derived from the Greek god Tantalus, who was known to be infamous for his attempts at stealing ambrosia and nectar (sweet wine).

Tantalum capacitors are often utilized in consumer electronics, including laptops, cellular phones, digital cameras, gaming consoles, and even circuit boards and printed circuit assemblies. The components are available in various sizes and package types, including surface mount and through- hole configurations. The components, depending on the type, can be composed of one or multiple layers of electro-active material. Types of tantalum capacitors can range from general purpose ones to those optimized for logic and memory.

The part number 199D105X0035A2B1E3 specifically refers to an axial tantalum capacitor with a 105 degree Celsius maximum operating temperature. The capacitance is 35 microfarads and the part is rated for an AC voltage of 6.3 volts.

The working principle of tantalum capacitors is based on the property of the material from which they are constructed—tantalum. It has a unique property in which it can attain a dielectric strength that is very high when the material is exposed to electrical current. Essentially, the tantalum capacitor is composed of two layers of conductive material, a dielectric layer between them, and a dielectric film that creates an electrical field between the two layers.

When an electrical current passes through the capacitor, the electric field causes a charge to build up in one layer while the other layer is discharged. This is a reversible process, which means that when the electrical current is removed, the charge on either layer switches places. The electrical field set up between the two conductive layers of the capacitor is known as its capacitance, which is a measure of the amount of charge a capacitor can store.

In real world applications, tantulum capacitors are used for signal filtering, signal coupling, smoothing out power supply lines, preventing signal interference, and providing energy storage. The components are also used in pulse power applications to provide high-current charge storage for a relatively short period of time.

In summary, tantulum capacitors are small and versatile electronic components made from the metallic element tantalum, primarily utilized in the electrical industry. The capacitor type with the specific part number 199D105X0035A2B1E3 is an axial type with a maximum operating temperature of 105 degrees Celsius, and a capacitance of 35 microfarads. The working principle of the capacitors is based on the unique property of the tantalum material, which creates an electrical field between the two conductive layers. The components are used in various consumer electronics, and for signal filtering, signal coupling, smoothing power supply lines, and more.
