Tantalum Capacitors

Tantalum capacitors are electronic components that use tantalum to store energy. As a type of capacitor, they are used to store dynamic and static electrical charge. A capacitor is an electronic component that stores energy and is composed of two or more electrodes, separated by an insulating material, called a dielectric. Tantalum capacitors are named due to their use of tantalum as the dielectric, which has a high dielectric strength and is highly efficient at storing an electrical charge.

Tantalum capacitors are typically used in signal conditioning applications and for decoupling circuits. They are extremely reliable and provide a number of benefits. Depending on the application, tantalum capacitors can either come in the form of wet tantalum capacitors, which utilize a liquid electrolyte, or solid tantalum capacitors which use a solid electrolyte.

The part number 199D105X5035A7B1 is a solid tantalum capacitor. This means that the capacitor uses a solid or non-liquid electrolyte. With this type of capacitor, when it is subjected to high temperatures the capacitor\'s electrolyte does not leach out. This reduces the risk of leakage current and increases the reliability of the capacitor. This type of capacitor is ideal for applications where reliability, such as memory protection circuits in computers and smart phones is important.

The most common type of solid tantalum capacitor consists of a tantalum pentoxide layer that is derived from tantalum powder. The powder is compressed between two electrodes and an anode which is responsible for creating a stable capacitor. To prevent dielectric breakdown, the anode is sealed inside the casing of the capacitor, protecting it from environmental factors such as moisture, oxygen and other gases. The anode also acts as a barrier between the ta ntalum oxide layer and the electrolyte that is used to store the electrical charge.

The working principle of a tantalum capacitor is simple but highly efficient. When a voltage is applied to the capacitor, the electrons in the tantalum oxide layer become charged and create a static electric field. This electric field is then stored in the electrolyte, resulting in an increase in the stored energy. When a reverse voltage is applied, the electrons in the oxide layer become oppositely charged, creating a field that is opposite of the original field. This results in a decrease in the stored energy, allowing the capacitor to quickly discharge. Tantalum capacitors can also be used to filter out unwanted noise and electrical interference.

Overall, tantalum capacitors are extremely reliable and highly efficient at storing and discharging energy. They are used in a wide range of applications where reliability is important, such as memory protection circuits, for filtering out unwanted noise, and for decoupling circuits. The part number 199D105X5035A7B1 is a solid tantalum capacitor, which is ideal for applications that require a high degree of reliability.
