Tantalum Capacitors

Tantalum capacitors are important for a variety of electrical applications. The constant demand for increased electrical performance from electronic components has seen their popularity recently grow among designers of high performance systems. With the right application, tantalum capacitors provide designer solutions for everyday requirements in power distribution and signal processing. The 199D186X9025D6B1 capacitor provides a case in point.

199D186X9025D6B1 Application Field & Working Principle

The 199D186X9025D6B1 is a tantalum capacitor designed for use in complex precision electronic systems. It has a minimum of 6.3VDC working voltage and has a maximum capacitance of 180μF. Its main application is in power management applications. These can include power supplies, automotive infotainment systems, and industrial computers.Tantalum capacitors work in a manner that is similar to other types of capacitors, such as ceramic or paper-in-oil types. In a tantalum capacitor, an anode and a cathode are placed in contact with an electrolyte, which is usually a paste or a liquid. As electrical current flows into the capacitor, an electric potential builds up at the metal plates which creates an electrical field across the electrolyte. This electric field causes ions to migrate through the electrolyte, creating a charge at the plates. This charge is stored as electrical energy called capacitance. As the voltage across the capacitor increases, the capacitance will also increase. When the voltage across the capacitance becomes sufficiently high, it will be discharged, and the capacitance will begin to decrease.Tantalum capacitors are low ESR (equivalent series resistance) components which means they are able to carry higher currents than other capacitor types and suffer less from excess heat due to a low power loss. Furthermore, tantalum capacitors have low DF (Dissipation Factor) and low impedance characteristics. The 199D186X9025D6B1 capacitor also features a low ESR due to its use of solid MnO2 as the primary dielectric, and a CTH hafnium layer, making it particularly suitable for high frequency applications.

The Advantages of Tantalum Capacitors

One of the main advantages of tantalum capacitors is that they have a high capacitance to volume ratio. This allows them to be used in tight, space limited environments, such as in cell phones and other small devices. Tantalum capacitors also tend to be more reliable than other types of capacitors as they are usually less prone to failure due to voltages sag, short circuit, or overheat. This is due to their solid construction and low ESR.The 199D186X9025D6B1 capacitor is small yet powerful, making it ideal for use in situations where space is limited. Its high capacitance to volume ratio ensures that it still delivers high performance within its small confines. With its low ESR qualities, it is also suitable for use in high frequency applications.

Conclusion

Tantalum capacitors are a versatile and reliable choice for many applications. The 199D186X9025D6B1 capacitor is a prime example of this and is well suited for use in a variety of situations. With its small build and low ESR, it is able to provide a reliable and efficient power and signal management solution for both space-restricted and high-frequency applications.
