Tantalum capacitors, sometimes known as tantalum electrolytic capacitors, are one of the most common electronic components used in modern electronic circuits. These capacitors are typically made up of two thin metal plates, one of which has an insulating dielectric material between them, although there are also solid and hybrid versions available.

The capacitor code T322B335K020AS is unique to the size, type and rating of the capacitor, and can be broken down into individual parameters. The first character, “T”, denotes the type of capacitor, in this case, Tantalum. The second and third characters, “32”, represent the capacitor’s maximum working voltage. The fourth character, “2”, signifies the capacitor’s dielectric material, in this case, an oxide. The fifth and sixth characters, “B3”, signify the capacitor’s physical length and diameter, respectively. The seventh and eighth characters, “35”, denote the capacitance value (in microfarads). The ninth character, “K”, indicates the tolerance of the capacitance value; in this case, it is +/- 10%. The last two characters, “20”, refer to the temperature coefficient of the capacitor; in this case, it is +/- 20ppm/oC.

Tantalum capacitors are widely used in consumer electronics, communications equipment and aircraft electrical systems due to their small size, high reliability and relatively low cost when compared to other capacitor types. They are mainly used for filtering and signal coupling applications, where their low equivalent series resistance (ESR) and high dielectric absorption ratio are highly desirable. In addition, tantalum capacitors have great stability over a wide temperature range, making them ideal for use in temperature-sensitive applications.

Tantalum capacitors offer a number of advantages over other types of capacitors, including low ESR and high capacitance values per unit volume. Unlike electrolytic capacitors, they do not require periodic recharging, and their small size and light weight make them ideal for applications which require high capacitance values in a space-constrained environment. Additionally, tantalum capacitors can be made in either cylindrical or flat-pack (chip) configurations.

Tantalum capacitors work by using a dielectric material to insulate the two metal plates, allowing only one of the plates to store electrical charge. When a voltage is applied across the plates, it creates an electric field, causing the electrons to move from one plate to the other. This creates a buildup of electrical charge which is stored in the capacitor until the applied voltage is removed.

In summary, the T322B335K020AS is a tantalum capacitor with a voltage rating of 32V, a dielectric material of oxide, a physical size of 3mm x 5mm, a capacitance value of 35μF, a capacitance tolerance of 10%, and a temperature coefficient of 20ppm/oC. This type of capacitor is widely used in consumer electronics, telecommunications, and aerospace applications due to its high reliability, low ESR and small size. Its working principle relies on creating an electric field between two metal plates and storing the electrical charge via a dielectric material.
