Tantalum Capacitors

Tantalum capacitors, sometimes referred to as ‘tantalum electrolytic capacitors’, are a type of component that derives its name from the mineral, tantalum, which is used in its construction. This component allows for efficient energy storage and, consequently, for the advancement of many electrical circuits. In this article, the application field of a particular type of tantalum capacitor, the M39003/01-2650/TR, will be discussed in detail, as well as the capacitor’s working principle.

Overview

The M39003/01-2650/TR is a tantalum capacitor in axial lead form with a capacitance value of 100 µF and rated voltage of 25 V. This capacitor is sealed with a flame retardant epoxy resin (SMD type E) and is also designed with built-in impedances in order to reduce electrical noise from other components. The capacitor can be used in applications ranging from 25°C to +85°C (surface-mount type) or -55°C to +85°C (through-hole type). Further specifications of the capacitor can be found in the manufacturer\'s datasheet.

Application Fields

The M39003/01-2650/TR tantalum capacitor can be used in a broad range of applications. It can be used to provide power decoupling in digital circuits, voltage smoothing, signal buffering, and energy storage. Due to its small size and low price, it is also widely used in portable devices such as multimedia players, mobile phones, portable computers, and calculators.

The capacitor can also be used in automotive electronic control units such as ABS, traction control, and oil pressure management systems. The component is also found in many other automotive applications such as airbag, cruise control, transmission, and engine control. By providing stable low-frequency power, the capacitor helps to maintain system reliability and reduce failures.

Working Principle

The working principle of a tantalum capacitor is based on the properties of the material, tantalum, from which it is constructed. The metal is doped with oxide to form a semiconductor with a capacitance range between 1 nF and 25 µF. The capacitor is then constructed in a spiral form, with the winding separated by an insulating material such as oil or resin.

When a voltage is applied across the metric capacitor, it causes a potential difference to form between the two layers of the winding. The difference in potential causes charge to be stored on both sides of the winding, which, in turn, creates an electrostatic field. This field acts as a barrier, preventing the movement of any external currents and allowing for energy to be stored in the form of an electric field.

Conclusion

The M39003/01-2650/TR tantalum capacitor is a component that can be used in a variety of applications due to its small size and low price. The control principles of the capacitor are based on the properties of the material from which it is constructed, tantalum, and a potential difference forms between the two layers of the winding when voltage is applied. This component allows for efficient energy storage, thus allowing for the advancement of many electrical devices.
