Tantalum Capacitors

The 199D225X9025A9V1 capacitor is a type of electronic component categorized within the Tantalum capacitor family. These capacitors are primarily used to store an electrical charge and regulate the current passing through an electrical circuit. Tantalum capacitors are suitable for high-frequency applications, due to their relatively high capacitance, fast response times to changes in capacitance and ultra-low ESR values. They are closely related, and sometimes interchangeable, with electrolytic capacitors.

Parameters and Specifications

Tantalum capacitors come in two different forms, Solid and Wet. The inductor is also referred to as a “chip”. The basic shape of this type of capacitor is a cylinder with a metal end that is connected by two metal plates. Within the middle of this structure, a tantalum-based powder material is sandwiched between two electrodes. The 199D225X9025A9V1 is rated for a voltage of 25V and has a capacitance of 225uF.

The size of this capacitor is quite small and it is generally seen in the range of 2mm × 3.2mm. The typical working temperature range for tantalum capacitors is -55 to 125°C. The temperature coefficient of this type of capacitor is typically in the order of ±30ppm/°C. Furthermore, the insulation resistance of the capacitor is typically around 1000MW, at 25°C.

Design Considerations and Applications

The packaging of this type of capacitor is mainly dependent on the use. For example, if it is intended to be a mobile phone part, then it might have a conventional leaded package. If being used as a power supply part in a PC, then it might have a surface-mount package.

Tantalum capacitors are extremely useful for applications that require the capability to control high currents and handle high voltages. These type of capacitors are often used in filtering operations, and are also used in the voltage-stabilization circuits.

In addition, the 199D225X9025A9V1 is well-suited for use in high-sensitivity electronic equipment such as receivers, signal processing devices, and amplifiers. They are also popular for decoupling operations. In decoupling circuits, the capacitors are used to improve signal-to-noise ratio by electronically eliminating signals at higher frequencies.

Working Principle

Tantalum capacitors operate in a fashion similar to electrolytic capacitors, but the use of tantalum oxide instead of an electrolyte makes them more tolerant to environmental conditions such as temperature and humidity. In a tantalum capacitor, an electrolyte is introduced into the capacitor, between the two oppositely charged plates. This electrolyte serves to discharge any electric charge stored in the capacitor.

The electrical impedance of the electrolyte in the capacitor is much lower than that of the air, meaning that the current can flow freely through the capacitor, allowing for a large amount of energy to be stored in a small area. This makes tantalum capacitors useful for high-energy applications. When a voltage is applied to the two electrodes, a current passes through the electrolyte, allowing the charge stored in the capacitor to be released.

Conclusion

The 199D225X9025A9V1 is a type of tantalum capacitor, that is suitable for high-frequency applications due to its large capacitance, fast response times and low ESR values. It is used in a variety of applications, including power supply circuits, signal processing, and decoupling operations. Its operation is similar to that of an electrolytic capacitor, but it is more tolerant to environmental conditions such as humidity and temperature.
