Tantalum Capacitors

Tantalum capacitors are one of the most popular types of capacitors used in various electronic circuits. This is because they offer excellent performance, energy efficiency and reliability. Tantalum capacitors have a wide range of applications and they can be used in a variety of different markets, including telecommunications, automotive, industrial, medical and avionics.The outer casing of a tantalum capacitor consists of two tantalum powder metallurgically bonded together to create an oxide and an anode. A dielectric layer, usually made of a niobium-titanium alloy, is sandwiched between the two layers. The tantalum is then sealed in a non-conductive casing to create a robust and reliable component.The code 199D686X0016E6B1 is used to identify the size and type of a particular tantalum capacitor; specifically this code refers to a 6.8μF tantalum capacitor which is an Electrolytic Polarized type. The first two characters (19) of the code refer to the size of the capacitance which is 6.8μF, the third character (D) refers to the Polarization (D- Polarized), and the remaining characters refer to the type of termination, which in this case is 6 pins. The electrical characteristics of such capacitors are determined by the type of dielectric layer and the structure of the capacitor. The dielectric layer, which is made up of niobium-titanium alloy, has a higher dielectric constant than other materials. As a result, the amount of electric current passing through the capacitor is reduced and therefore the amount of electric energy that is stored within the capacitor is increased.The construction of a tantalum capacitor also plays an important role in determining the working principle of the component. The two electrodes are arranged in such a way that when a voltage is applied across them the oxidation layer created on the material becomes conductive and allows current to pass through the capacitor. This, in turn, creates a storage element which can be used to store energy.Due to their high strength and reliability, tantalum capacitors have become an integral part of many electronic circuits used in the modern world. They are commonly used in the telecommunications industry, and are found in many avionics, medical and automotive applications. Their construction and design allow them to withstand harsh conditions and temperatures, making them highly suitable for use in many different types of boards, including printed circuit boards and flex circuits.Tantalum capacitors offer many advantages when compared to other capacitors. They have high power density, allowing them to store more energy in a smaller size, and they also offer high stability and reliability. Additionally, these capacitors can be operated in a wide range of temperatures and they are unaffected by changes in temperature and humidity. In conclusion, the 199D686X0016E6B1 code is used to refer to a 6.8μF tantalum capacitor. Tantalum capacitors offer many advantages due to their high capacitance, low leakage current and compact construction, making them one of the most popular types of capacitors used in all types of electronic applications.
