Tantalum capacitors are a type of electrolytic capacitor that offers superior performance to regular electrolytic capacitors. They use a tantalum oxide coating on the plates to provide excellent frequency characteristics and low leakage current. The F921D474MAA is a type of tantalum capacitor designed for use in analog circuits. This capacitor has a voltage rating of 6.3 Volts and a capacitance rating of 470 μF.

Application Field

Tantalum capacitors are commonly used in audio, radio, and other analogue applications where performance is critical. Its superior frequency characteristics make it perfect for high frequency switching, time delays, and signal processing. It is also well suited for applications that require extremely low leakage current, such as with medical or instrumentation equipment.

The F921D474MAA can be found in analog circuits such as radios, televisions, speakers, amplifiers and other audio equipment. It is also used in medical equipment, instrumentation, aerospace electronics, and power supplies. It is often used in combination with other components in order to optimize performance.

Working Principle

Tantalum capacitors work on the principle of dielectric absorption. The metal plate in the capacitor is coated with a layer of tantalum oxide. When a voltage is applied to the plates, electrons are driven into the dielectric causing an increase in capacitance. When the voltage is removed, the electrons are forced out of the dielectric and the capacitance returns to its original state.

The F921D474MAA capacitor is constructed with a tantalum anode and cathode placed in an electrolyte gel. The anode plate is coated with a tantalum oxide dielectric. When a voltage is applied, current flows across the plates forming an electric field. This electric field creates a capacitance which is then stored as electrical energy. This stored energy can then be released when needed.

Tantalum capacitors are also known for their low leakage current. This is due to the high quality of the dielectric employed in their construction. The tantalum oxide coating on the anode plates provide excellent frequency characteristics and low leakage current, which make them a great choice for analog applications.
