Tantalum capacitors are widely used in today’s electronics as a passive component to store and release energy. The specific model F980G686MSA is a non-polarized, electrolytic capacitor that is designed to have low leakage current and better stability in temperatures between -55°C and 125°C. It has a capacitance range of 0.22 to 47 µF with tolerances up to 10%.

To manufacture these capacitors, tantalum oxides are mixed with carbon-based activators that acts as the dielectric. This material is then formed into a pellet and is inserted into an anodized cylinder-shaped container with an electrolyte. This package can be tubular, chip, or dipped type. By connecting two electrodes to the ends of the package a double-layer capacitor is formed.

The F980G686MSA is a surface mount type capacitor that has the unique feature of being non-polarized. This is achieved by having the cathode layer made of tantalum nitride. The cathode layer acts as an electrical insulator that keeps the support plates and other components from touching each other and becoming energized. The anode layer is made of a porous tantalum layer that is impregnated with the electrolyte.

The working principle behind the F980G686MSA capacitor is that electric current will flow into the capacitor through one of the two electrodes. This current charges up the plate of the capacitor that is closest to that electrode, creating a positive charge. As more current flows in, the plate will become more positively charged which creates a difference in the charge buildup between the two plates. This creates an electrical field which stores energy.

When the current is removed from the capacitor, the positive charge from the plate that was closest to the electrode will slowly reduce since there is no longer an electric force pushing against it. This creates a negative charge on the opposite plate which is now being pushed away by the electric field. As the charge builds up, it eventually matches the charge of the positively charged plate, so the electric field is neutralized and the energy stored in the capacitor is released.

The F980G686MSA capacitor is specially designed to be non-polarized and to have low leakage currents. This makes it particularly suitable for temperature-sensitive applications such as local vehicle climate control systems or automotive entertainment systems. It can also be used in medical systems that require low power consumption, as well as in a wide range of industrial applications.
