Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, which have the highest volumetric efficiency of any style of capacitor available, meaning that more capacitor can be stored in the same amount of space. This makes them ideal for portable electronics, where space is often at a premium. Tantalum capacitors are also rated for high temperatures, so they are well-suited for high-heat applications, such as some military, aerospace, and automotive applications.

The construction of a tantalum capacitor consists of 2 electrodes, an anode and a cathode, separated by an electrolytic dielectric material. When the capacitor is charged, an electric field forms between the 2 electrodes, resulting in an electrical charge being stored in the capacitor. The anode and cathode of a tantalum capacitor are made of a tantalum core, which is then coated with a dielectric oxide layer, either manganese dioxide, or niobium oxide for low-voltage capacitors. This oxide layer acts as the dielectric material, as well as serving as an electrolytic agent, allowing a current to flow from one electrode to the other.

The 199D105X5035A2B1 is a specific type of tantalum capacitor that has a variety of uses in both industrial and consumer applications. It is a low profile, dipped Tantalum Capacitor with a voltage rating of 35 Vac and temperature coefficient of -160ppm/K. This type of capacitor is often used in applications that require low ESR, such as high-performance, low-noise switched-mode power supplies and in high-volume consumer products. It is also often used in automotive, military and aerospace applications, due to its high tolerance to temperatures, as well as its small size.

The working principle of the 199D105X5035A2B1 is the same as any other tantalum capacitor, where an electric field is formed between the 2 electrodes, when the capacitor is charged, resulting in an electrical charge. The dielectric material prevents leakage and ensures the capacitor can properly store and discharge the electrical charge. The low ESR of the capacitor ensures that the capacitor can respond to sudden changes in current and voltage and will be able to cope with high frequencies. The small size of the capacitor means that it can easily be used in a wide range of applications, as it can be placed in tight spaces with little issue.

In conclusion, the 199D105X5035A2B1 is a type of Tantalum Capacitor, which makes it ideal for a wide range of applications, due to its low ESR, small size and its ability to operate at high temperatures. Its working principle is the same as any other capacitor, where an electric field is formed between the 2 electrodes, when the capacitor is charged, resulting in an electrical charge being stored. It is commonly used in applications that require low ESR, such as high-performance switched-mode power supplies, automotive, military and aerospace applications.
