The F971E475MCC series of tantalum capacitors can be used for high voltage and high current applications. They have a high ability to store charge compared to other capacitors and can handle higher voltage levels than most other capacitors. This makes them ideal for applications such as fuel injection and control systems, automotive and aerospace applications, power supplies, battery backups, and more. The F971E475MCC series of tantalum capacitors is available in low and medium load types and is available with nickel-plated terminations for improved corrosion resistance and better electrical performance.

Working Principle of Tantalum Capacitors

Tantalum capacitors are electrolytic capacitors that use a thin oxide layer on the surface of a tantalum core as the dielectric. This oxide layer acts as a barrier to the flow of electrical current, allowing the capacitor to store a charge and discharge it on demand. The oxide layer is formed by the application of a voltage to the capacitor in a process called anodization, which creates an electric field on the tantalum core that breaks down the tantalum into positively and negatively charged ions. The positively charged ions bond to the tantalum core to form the insulating layer, creating the capacitive effect.

The charging process for a tantalum capacitor is straightforward and involves a pulsed direct current, often supplied by a power supply. The capacitor will absorb the charge until it reaches its full capacity, at which point it will reverse the current and discharge the stored energy. This process can be repeated multiple times, allowing the capacitor to store energy and discharge it on demand.

Tantalum capacitors are very efficient in converting electrical energy into stored charge. This makes them ideal for applications where large amounts of energy must be stored in a small amount of space, as well as for applications where a large amount of charge must be delivered quickly. Tantalum capacitors also have a number of other advantages, including long life expectancy, low leakage current, and low operating temperature coefficients.
