Tantalum Capacitors: F981A226MSA Application Field and Working Principle

Tantalum capacitors are widely used in electronic products and circuits, thanks to their high capacitance-voltage (CV) ratio, small size, and high performance. The F981A226MSA series is one of the most popular tantalum capacitors on the market, preferred for its excellent electrical characteristics, low profile, and competitive price. This article will focus on the application fields and working principle of the F981A226MSA series.

Application Fields of F981A226MSA

The F981A226MSA series is a wet slurry (solid) tantalum capacitor that is most commonly used in a variety of commercial and industrial applications, including military, aerospace, robotics, communications, and automotive. It is also extensively used in some household applications, such as hearing aids, marine electronics, and medical equipment.The F981A226MSA series has excellent electrical characteristics, making it an ideal choice for applications requiring low equivalent series resistance (ESR), low equivalent series inductance (ESL), long-term reliability, and high current ratings. It is also advantageous for applications requiring a capacitor with a long life cycle since it is designed to integrate with a high temperature stable dielectric.Because of its small size and low profile, the F981A226MSA series is often used for tight-space applications. Its axial lead design also makes it easy to install in circuits.

Working Principle of F981A226MSA

The F981A226MSA series consists of a small cylindrical metal cup, filled with an electrolytic slurry, with a positive and negative output terminal at either end. The positive terminal is identified by a “+” symbol while the negative terminal is identified by a “-” symbol. The internal mechanism of a wet slurry capacitor is simple. In a direct current (DC) circuit, electrical charges accumulate on the surface of two metal plates connected to each of the two terminals. The charges accumulate until an equilibrium is established, at which point the capacitor exhibits its capacitance.When a voltage is applied to the capacitor, the charges stored in the capacitor will leak, creating a current. This current will cause a reaction in the electrolyte to transfer more charges to the capacitor, maintaining the charge balance. This process is known as the capacitance refreshes. The internal structure of the F981A226MSA series is designed to ensure that the capacitor is able to maintain its capacitance under a wide range of operating conditions. The thickness of the dielectric is also adjusted to ensure that the capacitance is stable over a range of temperatures.

Conclusion

The F981A226MSA series is a high-quality wet slurry tantalum capacitor, designed for applications that require excellent electrical characteristics, long-term reliability, low profile, and competitive pricing. It is well-suited for use in commercial and industrial applications, such as military, aerospace, robotics, communications, and automotive, as well as in some household applications, such as hearing aids, marine electronics, and medical equipment. The F981A226MSA series is able to maintain its capacitance through a capacitance refreshes process, and its internal structure is designed to ensure stable capacitance over a wide range of temperatures.
