Tantalum Capacitors

Tantalum capacitors are one of the most widely used capacitor type today. They are ideal for use in a wide range of applications, from power supplies to audio circuits, and have a proven track record for providing reliable performance and long service life. The specific type of tantalum capacitor in question here is the 195D225X0020D2T which is an electrolytic capacitor.

Application Field

The 195D225X0020D2T is used in many portable and desktop devices, due to its ability to store significant energy in a small form factor. Low power circuits, such as audio amplifiers, also use this type of capacitor as it is able to store and release power effectively. Its power characteristics make it suited for use in low voltage, and low frequency applications such as those found in mobile phones and PDAs.

The breadth of use cases for which the 195D225X0020D2T capacitor is suited make it a popular choice for applications in appliances, battery-powered ones in particular. Its ability to remain charged even when the power supply is disrupted makes it very useful for maintaining a consistent power supply to any electrical device. Its high ripple current capability also makes it suitable for use in power supplies and filters where a steady current is required.

Working Principle

At the heart of the 195D225X0020D2T capacitor is its ability to store significant energy in a very small form factor. This is achieved through its electrolyte, which consists of a combination of liquid and solid electrolytes. This mixture enables the capacitor to store energy through the process of creating an electrical charge.

When a voltage is applied to the capacitor, the electrolyte medium creates an electrostatic field that distorts the surface of the electrodes and increases their charge. This charge is then stored in the capacitor. The reverse process most often occurs when the capacitor is discharging, where the electric field between the electrodes is disrupted and the stored energy is released.

Tantalum capacitors are generally recognised as being more reliable than other types of capacitors. This is mostly because their construction is more robust and can withstand a wide range of temperatures and environmental elements. This makes them ideal for use in applications where failure is not an option, such as medical devices and critical power supplies.

Conclusion

The 195D225X0020D2T tantalum capacitor is an incredibly versatile component, with applications ranging from power supplies to audio. The fact that it is able to withstand a wide range of temperatures and environmental elements, whilst being able to store significant energy in a small form factor, make it an extremely desirable component for use in many applications.
