Tantalum capacitors are an ideal choice for many electronics applications, providing high capacitance, small physical size, and excellent electrical characteristics. The 299D476X9010DB6 is a tantalum capacitor with a wide range of applications, and a straightforward working principle.

Overview

The 299D476X9010DB6 is a surface mount aluminum electrolytic capacitor. It uses tantalum as the charge storage medium, and has a capacitance range from 47µF to 470µF, at a max voltage range of 6.3 VDC to 10 VDC. The case size is EIA 1206, or 2.8 x 1.5 mm in physical size. The capacitance tolerance is ±10%, and the rated voltage is DC. The products are RoHS compliant.

Applications

The 299D476X9010DB6 is suitable for a wide range of applications, including power supply input/output decoupling, signal conditioning, filtering, and charge pumps in industrial and consumer electronic products. Due to its very small physical size, it is also ideal for applications where space is limited, such as in mobile phones or handheld devices.

Working Principle

The essential working principle of the 299D476X9010DB6 is based on two key elements: a thin film of tantalum on a substrate, and a solid electrolyte, usually manganese dioxide. When a voltage is applied to the device, electrons are attracted to the tantalum film. This creates an electric field, which in turn causes an electric charge to accumulate on the surface. The specific capacitance of the device depends on the area of the tantalum film, and the thickness of the dielectric layer.

Benefits

Tantalum capacitors offer several benefits over other types of capacitors. They have a wide range of capacitance values, allowing for very tight capacitance tolerances. In addition, they have a wide operating temperature range, low equivalent series resistance (ESR), very low leakage current, and excellent electrical stability. Additionally, tantalum capacitors are highly reliable, and have an extremely long life expectancy – typically up to 50,000 hours.

Conclusion

The 299D476X9010DB6 is a versatile tantalum capacitor designed for a wide range of applications. It offers a small physical size, high capacitance, excellent electrical characteristics, and a long life expectancy. Furthermore, it offers superior performance over other capacitors, making it the ideal choice for many electronics applications.
