Tantalum Capacitors

Tantalum capacitors (also known as tantalum electrolytic capacitors) are a type of capacitor with a tantalum tantalum metal oxide as an anode, and are widely used in electronic equipment. The 5-1879063-2 refers to a specific type of tantalum capacitor with an anode built from two tantalum plates separated by an oxide-coated dielectric insulator and a solid conductive electrolyte.The field of application of tantalum capacitors is very broad, from raw material recycling to basic electronic components to military equipment. Nearly all consumer electronic devices, computers, and telecommunications equipment have at least minor usage of tantalum capacitors. In addition, tantalum capacitors are being used increasingly for energy storage due to their unique characteristics, such as a low equivalent series resistance (ESR) and very high self-inductance.The working principle of a tantalum capacitor is similar to that of any other capacitor. A tantalum capacitor consists of two plates separated by an oxide-coated dielectric insulator and a solid electrolyte. The dielectric insulator allows for an electrical current from one plate to the other. When a voltage is applied to the capacitors, an electric-field is generated, and this electric-field produces a charge separation between the two plates, thereby creating an electrostatic field. This electrostatic field then induces an electrical current in the capacitor. The electric current then dissipates as the charge stored in the capacitor is released.Tantalum capacitors come in three main varieties: solid, sintered and molded. Solid tantalum capacitors contrast from other types in the fact that they are constructed with tantalum plates embedded in a solid molded rubber container, rather than sintered or molded. This allows the capacitor to be constructed with a relatively large dielectric insulator, resulting in higher capacitance. Sintered tantalum capacitors are made with a mixture of compressed metal powder and active agent, usually manganese dioxide, sealed within a solid block of material, such as tantalum. The whole is then heated and the active agent produces a protective oxide layer on the surface of the electrode. The capacitance rating of sintered tantalum capacitors is higher than that of molded varieties, typically up to several times higher.Molded tantalum capacitors have the same construction as solid types, but the dielectric insulator is enclosed in an epoxy body rather than rubber. By doing so, the dielectric insulator can be compressed to a much smaller size, allowing for higher capacitance ratings, typically up to several thousand Farads. Tantalum capacitors are also used in combination with aluminum electrolytic capacitors.Tantalum capacitors have a wide range of applications. For example, they are used in automobiles for solenoids, and in medical devices for rectifiers and filters. In addition to that, they are also used in high-performance computers and other equipment for power management applications. The main advantages of tantalum capacitors are their high capacitance and efficiency levels, high reliability, very low ESR, and very high self-inductance. They also perform quite well in extreme temperature and environmental conditions, and are very robust. However, one of the main drawbacks of tantalum capacitors is their cost. They are typically the most expensive capacitor on the market, and can be up to several hundred times more expensive than other capacitor types.Overall, tantalum capacitors are very versatile and reliable components that can be used in many different applications. They offer clear advantages over other types of capacitors, such as their very low ESR, high capacitance levels, and very high self-inductance. These features make them an ideal choice for applications where reliability and performance are of paramount importance, such as medical devices, automobiles and computers. However, their cost can be a prohibitive factor in some applications.
