Tantalum capacitors are electronic components that use tantalum metal to store electrical energy. They are used in various applications including computers, cell phones, and portable electronics because of their high volumetric efficiency, robustness and stability. The F931A476KBA is one type of tantalum capacitor that is extensively used in various industries and applications. This article will explore the application fields and working principle of the F931A476KBA tantalum capacitor to provide a detailed insight into its uses and capabilities.

The F931A476KBA tantalum capacitor is a surface-mounted capacitor with a 12.5 V working voltage and a 4.7 µF capacitance. It is made up of a solid tantalum anode and a thin dielectric oxide layer which separates the anode from the cathode. The anode is made of pressed and sintered tantalum powder while the cathode is a solid silver-plated manganese dioxide (MnO2) which acts as the electrolyte. The design of the F931A476KBA ensures that it is reliable, robust and stable and is able to reliably store and release energy for a long period of time.

The F931A476KBA tantalum capacitor can be used in a wide range of applications due to its reliable and robust design. Industry-wise, it is widely used in aerospace, automotive, consumer electronics, industrial and medical markets. Some specific applications include high-frequency filter networks, timing circuits, memory backup systems, military and avionics applications, and automotive power source and engine circuits. The F931A476KBA tantalum capacitor is also ideal for portable medical equipment, consumer electronics and smartphones as it provides reliable and stable power within a small form-factor.

When the F931A476KBA tantalum capacitor is used, the initial charge is provided by the current flowing through the capacitor which is determined by the applied voltage. When power is applied, positively charged ions on the tantalum anode are attracted towards the negatively charged MnO2 cathode. This forms an oxide film at the surface of the anode that acts as the dielectric between the anode and the cathode. This dielectric provides a barrier between the electrons of the anode and the electrons of the cathode, which is necessary for the capacitor to store electricity.

When the capacitor is discharged, the attraction of charges is reversed, causing the MnO2 layer to become an anode and the tantalum anode to become a cathode. This causes the oxide film to dissolve, allowing the electrons to flow out of the capacitor in a process known as a capacitive discharge. The capacitive discharge of the F931A476KBA is smooth and linear which makes it ideal for timing and pulsing circuitry.

In conclusion, the F931A476KBA tantalum capacitor is an electronic component that provides reliable and robust energy storage for many applications. Its 12.5 V working voltage, 4.7 µF capacitance and capacitive discharge operation make it perfect for a variety of industries and applications. With the capacity to store and release energy reliably, the F931A476KBA is the perfect tantalum capacitor for aerospace, automotive, consumer electronics, industrial and medical markets, as well as portable medical devices, consumer electronics and smartphones.
