Tantalum Capacitors: M39003/03-0254/TR Application Field and Working Principle

Introduction:

Tantalum capacitors are a type of electrolytic capacitor, used mainly to store electrical energy. These capacitors contain a tantalum metal oxide anode and a solid-polymer anode, and are often employed to store energy in military and aerospace components, radio transmission and infra-red equipment, automotive and PC boards, and as clock oscillators. The tantalum capacitors M39003/03-0254/TR are typically used for Energy Storage and Resets, and their application fields and working principles are discussed further in this article.

Application Fields:

The M39003/03-0254/TR tantalum capacitors are used in energy storage systems, where they are commonly employed to provide energy to a circuit over periods when other sources of power are unavailable. These capacitors are also used in Reset circuits, whereby the energy stored by the capacitor is used to reset the circuit after power is applied to the system or when the system has experienced a power interruption. The M39003/03-0254/TR capacitors can be used in power supplies, amplifiers, signal processors, digital control systems, embedded systems, and other electronics. In automotive applications, they have been used as memory back-up devices for temperature control units and navigation systems. Additionally, they have been utilised in PC boards and laptops, which may require a reset signal after a power failure or low voltage.

Working Principle:

The M39003/03-0254/TR tantalum capacitors rely on the principle of electrostatic energy, whereby energy stored in an electric field between two plates is used to store a charge. The capacitor’s anode is a highly conductive semiconductor containing a thin oxide layer, while the cathode is composed of a solid-polymer anode. This type of capacitor is conventionally polarised and is rarely used with alternating current (AC) systems. When a voltage is applied to the terminals of the capacitor, an electric field is generated between the plates. This electric field can store energy, just like in a conventional battery. When the voltage is removed, the energy stored in the capacitor is still available and can be used to provide a current flow through the system.

Conclusion:

The M39003/03-0254/TR tantalum capacitors are typically used for energy storage and reset applications. They rely on the principle of electrostatic energy and are composed of a conductive tantalum oxide anode and a polymer-based cathode. These capacitors can be used in a variety of power supply, automotive, embedded system, signal processor, and other applications.
