Tantalum capacitors are widely used in telecommunications, computer, audio and automotive industries, and the F921C475MBA is a typical and most common type of them. The device features a solid polymer and Mn02 construction, so it is usually used for military and space applications. With these features, the F921C475MBA is able to provide superior voltage regulation, good stability and reliability, and also for its small size, it is suitable for surface-mount applications.

The capacitance of the F921C475MBA is 75 microfarads, with a maximum operating voltage of 16 volts. It has a low Equivalent Series Resistance (ESR) of 0.41 ohm and a maximum operating temperature of 125℃. It is mainly used in switch-mode power supplies, DC/DC converters, rectifiers, and audio circuits. In addition, it also has a superior electrical characteristic, and is suitable for circuit operations in hostile environments.

The F921C475MBA is made of tantalum, an element of atomic number 73. The distinctive properties of tantalum make it an excellent material for making electronic components, such as capacitors and resistors. In a typical tantalum capacitor, an anode is made of tantalum powder, pressed into a pellet, and then sintered. A cathode is then made of MnO2 paste, and then a dielectric layer is formed between the anode and the cathode. This dielectric layer increases the capacitance of the device and is usually made of a special polymer. The total thickness of the dielectric layer is determined by the manufacturer.

The main purpose of the F921C475MBA is to store electrical energy in a device and release it as needed. When a voltage is applied to the capacitor, a current will flow through it, and the energy stored in the capacitor will increase. The capacitance is related to the area of the dielectric layer, the thickness of the dielectric layer, and the permittivity of the dielectric material. The operating temperature of the F921C475MBA is limited by its heating effects caused by power losses.

In conclusion, the F921C475MBA is a commonly used type of tantalum capacitor for military and space applications. It has a low equivalent series resistance, a maximum operating voltage of 16V, a 75 microfarad capacitance, and a maximum operating temperature of 125℃. Its small size and high reliability make it suitable for surface-mount applications in switch-mode power supplies, DC/DC converters, rectifiers, and audio circuits.
