Tantalum Capacitors

Tantalum capacitors are an important type of electronic component used in various circuit designs due to their many advantageous properties. The part designation of this capacitor is 199D474X0035A6V1E3 and its application field and working principle will be discussed in detail below.

Introduction to Tantalum Capacitors

Tantalum capacitors are an type of electrolytic capacitor that is constructed with an anode that is made up of powdered tantalum metal, a cathode plate made of an oxide of tantalum, an electrolyte such a liquid or a solid manganese dioxide, and a pair of external leads. This type of capacitor is a great choice for high stability and energy storage because it offers low equivalent series resistance (ESR) and low leakage current. Capacitors of this type come in a variety of sizes and voltages with some having higher maximum voltage and higher capacitance values than many other types of capacitors.

Application Field of 199D474X0035A6V1E3

Due to their desirable features, tantalum capacitors are used in a wide range of applications such as in decoupling and filtering. These components are especially useful for circuitry that needs to remain stable under changing conditions due to their low leakage current properties. Consequently, these types of capacitors are commonly used in mobile devices and automotive electronics. Additionally, they are suitable for use in space and aviation applications.

Working Principle of 199D474X0035A6V1E3

The working principle of this capacitor is based upon the concepts of capacitance and electric potential. As current flows through the external leads, it passes through the capacitor’s anode and cathode, creating a potential difference between them. This potential difference creates an electric field in the region between the anode and cathode, causing ions to form at each terminal. This creates the typical capacitive behavior in which energy is stored in the electric field between the anode and cathode, allowing it to be released or recharged at a later time.

Conclusion

Tantalum capacitors, such as the 199D474X0035A6V1E3, are an important type of electronic component due to their unique features and wide range of applications. Their form factor and construction allow them to store energy in an electric field and supply it when needed. With their low equivalent series resistance and low leakage current properties, this type of capacitor is often used in mobile device and other circuits that require high stability and consistent energy storage.
