Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, which uses tantalum as an anode. The surface of the tantalum pentoxide acts as the dielectric material of the capacitor. It has an extremely high capacitance for its volume, so it is used extensively in applications requiring very small size. It has excellent electrical characteristics that make it ideal for many demanding applications.

13008-040KESB Application Field and Working Principle

The 13008-040KESB is a range of small tantalum capacitors from Vishay. These capacitors are designed for applications such as power supplies, motors, amplifiers, computer peripherals, and other high-frequency circuits. The working principle of a tantalum capacitor is based on the capacitance of a dielectric material, in this case tantalum pentoxide. The 13008-040KESB range has an operating temperature range of -55°C to 85°C and a capacitance range from 1µF to 220µF. The capacitance and voltage capabilities of the 13008-040KESB range make it suitable for a wide variety of electronics applications.

The tantalum pentoxide dielectric can provide a high dielectric constant, meaning that capacitance can be maintained at very small sizes. This makes it particularly attractive for power supplies and other applications where space is at a premium. The 13008-040KESB range also has an operating voltage of up to 50 VDC, allowing for high current or high voltage applications. The capacitance is also very stable over temperature and long term use.

The 13008-040KESB range is an ideal choice for many electronic applications, providing high performance and reliable operation in a very small package. The cost of these capacitors is also relatively low compared to other types, making them an attractive option for high-end applications.
