Tantalum capacitors are passive electronic components composed of two electrically conductive layers separated by an insulating material known as a dielectric. Popular types of tantalum capacitors include wet and dry tantalum capacitors which are used in many applications. The T491R106K010AT is an example of a wet tantalum capacitor that has high-capacitance values in a low-profile package.

The application field for T491R106K010AT tantalum capacitors include space-limited applications such as notebooks, monitors, television sets, and other consumer electronics. This type of capacitor can also be used in battery-powered equipment, automotive electronics, and military applications. This capacitor is also suitable for use in portable medical devices and in high-temperature or high-humidity environments.

The working principle of a tantalum capacitor is based on the capacitive relationship between two conducting surfaces separated by an insulating material. In the case of the T491R106K010AT capacitor, the two conducting surfaces are polarized and operate similarly to a conventional electrolytic capacitor. The dielectric is constructed of manganese dioxide, and the polarization of the two conducting surfaces produces a potential difference across the capacitor. This potential difference enables the capacitor to store electrical energy.

The main differences between conventional electrolytic capacitors and tantalum capacitors are related to the nature of the dielectric materials. Unlike the aluminum oxide used in electrolytic capacitors, the manganese dioxide used in tantalum capacitors does not need to be continuously energized to maintain its electrical properties. This makes tantalum capacitors much more reliable than electrolytic capacitors as they can remain operational for very long periods of time.

T491R106K010AT tantalum capacitors have greater volumetric efficiency than other types of capacitors, making them ideal for space-limited applications. The lower profile of this capacitor is also beneficial in applications where circuit board area is limited. Its high-temperature and high-humidity operational characteristics make it suitable for use in additional challenging environments.

T491R106K010AT tantalum capacitors are used in a variety of consumer electronics applications, as well as in automotive electronics, military applications, and medical devices. The working principle of a tantalum capacitor is based on the capacitive relationship between two conducting surfaces separated by a dielectric material. The manganese dioxide used in this type of capacitor does not need to be continuously energized, making it much more reliable than electrolytic capacitors. Additionally, the lower profile and high volumetric efficiency of T491R106K010AT capacitors also make them ideal for use in space-limited applications.
