Tantalum Capacitors

Tantalum capacitors are a type of capacitor that consists of a tantalum dielectric material. This type of capacitor is mainly used in different types of industrial and consumer electronics. They are uniquely designed to store a large amount of energy in a small package.

The performance of a tantalum capacitor is quite impressive, as it not only provides good capacitance, but also excellent current leakage properties. This makes it ideal for many different applications. It offers excellent temperature stability and its operational life span can be much longer than other types of capacitors.

The primary application of a tantalum capacitor is in sensing and timing applications. It can also be used as a power back up, as it can be charged rapidly and stored for extended periods of time. It is widely used in digital circuits with high frequency requirements, such as in audio and video circuits, data communication devices, computers, and automotive electronics.

The basic construction of a tantalum capacitor is composed of two elements; a dielectric material and a metal electrode. The dielectric material is usually a wet or dry tantalum oxide. This type of oxide is highly desirable because it is non-conductive, has an extremely low dielectric constant, and can provide extremely high insulation resistance.

The case of a tantalum capacitor is made up of a hermetically sealed structure which is usually either a “foil” or a “pill”. A foil-type case is usually made out of anodized aluminum and is much smaller than a pill-type case. The pill-type case consists of a ceramic cylinder covered with a metal foil, and the two are sealed together with a ceramic sealant.

The working principle of a tantalum capacitor is the same as that of other capacitors. The two metal plates are connected to two opposite, yet equally charged conductors. When an external voltage is applied, the metal plates become oppositely charged, thus creating an electric field which can store an electrical charge. The capacitance of the capacitor then depends on the area of the metal plates and the distance between them.

Part number 199D105X9035A6B1E3 is a tantalum capacitor with a case size of 0805X9, a capacitance value ranging from 10 to 20uF and a voltage rating of 6.3 volts. This is a commonly used part in various consumer and industrial electronics, such as cell phones, stereo systems, DVD players and flash memory circuits.

Tantalum capacitors have become an essential part of industrial and consumer electronics, due to their excellent electrical characteristics and reliability. These capacitors are primarily being used in sensing and timing applications, as well as power backups, thanks to their superior current leakage characteristics, and their ability to store large amounts of energy in a small package.
