Tantalum Capacitors

Tantalum capacitors, also commonly referred to as tantalum electrolytic capacitors, are a type of capacitor that utilise an electrolyte, usually in a gel or as a solid mixture, as the dielectric between two small, metal plates called anode and cathode. This electrolyte is a conductor of electricity, allowing an electric current to flow between the two plates. This type of capacitor is generally considered to be a surface mount electronic component and is available in many different designs and configurations.

M39003/09-2059/TR Application Field and Working Principle

The M39003/09-2059/TR is a chip tantalum capacitor, used for applications that require high capacitance and low inductance. The device features anodized terminations, which allow it to be connected tightly to other components, while still maintaining its flexibility of use. This type of capacitor also features an oxide dielectric, making it suitable for high-frequency applications.

In terms of its working principle, when two metal plates are placed in close proximity and a voltage is applied across them, an electrostatic field is created which governs the flow of electrons between the two plates, forming an electrostatic charge. This charge then resides on the plates, creating an amount of stored energy referred to as capacitance.

The capacitance of a tantalum capacitor is dependent upon the area of the two plates and their distance apart. Generally, the capacitance increases with the level of voltage applied, and decreases as the temperature increases. The materials used in the construction of the capacitor also have an effect upon the level of capacitance the device offers, and so typically a combination of an anodized terminations and oxide dielectric is used in order for the device to offer a high level of capacitance.

These devices, or capacitors, are then used in applications that require high frequency electrical power, generally in the range of 10 Hz to 1 MHz. These applications cover a range of products including both consumer electronics devices, such as mobile phones, and military grade electronic equipment.

In conclusion, the M39003/09-2059/TR is a chip tantalum capacitor, which uses an oxide dielectric along with anodized terminations in order to offer a high level of capacitance suitable for high frequency applications. The device is used widely in both consumer and military grade electronic equipment.
