Tantalum Capacitors are electronic components with the highest reliability and thermal resistance, and the 299D series is one of the most popular families of such components. The 299D155X0050CB1 capacitor is a type of solid electrolytic tantalum capacitor used in a number of power supply applications due to its high capacitance, low ESR, and low profile. This article will discuss the application fields and working principle of this tantalum capacitor.

Application Fields

The 299D155X0050CB1 is specifically designed for power supply design and applications. In this capacity, it serves to provide a smooth, reliable output for systems requiring a stable power line. This includes personal computers, handheld electronics, power supplies, and a variety of other general purpose and automotive applications. The 294D155X0050CB1 is also suitable for use in remote battery power systems and embedded control systems, due to its low resistance, providing stable supply of power to many small circuits. Additionally, its low profile makes it ideal for surface mount electronics and high-density printed circuit boards.

Working Principle

Tantalum capacitor components like the 299D155X0050CB1 are constructed of a tantalum metal alloy as a core, which is then filled with a solid manganese dioxide electrolyte. The metal alloy acts as the anode, and is attached to one of the capacitor’s terminals, while the manganese dioxide acts as the cathode and is attached to the second terminal. Given its anodic and cathodic structure, the capacitor acts as a battery with a reversible charging/discharging ability, which is why it is commonly referred to as a “capacitor-battery”. The current is enabled to flow through the capacitor until the charge has been equalized and the voltages are the same, at which point the flow of current halts. Thanks to the use of a solid electrolyte, this type of tantalum capacitor has a higher capacitance-to-volume ratio compared to other capacitors and a very low Equivalent Series Resistance (ESR).

Conclusion

The 299D155X0050CB1 is an example of a solid electrolytic tantalum capacitor, commonly used in power supply applications. It is designed specifically to provide a reliable, smooth output voltage in a range of general purpose and automotive electronics. This device works by relying on a tantalum metal alloy and solid manganese dioxide electrolyte to create a battery-like structure, with a high capacitance-to-volume ratio and a very low ESR. As such, it is an incredibly reliable electronic component for power supply applications.
