Tantalum capacitors, also known as tantalum electrolytic capacitors, are one of the most widely used types of capacitors. The T491B105M035AG is a surface-mount low ac-current MnO2-type tantalum capacitor with a capacitance range from 0.2 μF to 2.2 μF. The capacitor has a rated voltage of 35V and a temperature range of -55°C to 125°C.

Tantalum capacitors are manufactured by depositing a layer of tantalum pentoxide on a metal base, which forms the dielectric. This is then covered by a conductive layer, typically manganese dioxide or conducting polymer, which forms the electrodes. The dielectric layer is extremely thin, typically only a few angstroms thick, allowing a large capacitance to be developed in a small package.

The T491B105M035AG tantalum capacitors provide high capacitance density in a small package and are well suited for filtering, decoupling, buffering and bypass duties. Its small size and high voltage characteristics make it particularly suitable for use in mobile phones and other portable electronics. The combination of low ESR and high capacitance also makes it suitable for use in power supplies.

The T491B105M035AG has a low equivalent series resistance (ESR), which enables fast energy storage and release. Moreover, it exhibits excellent high frequency characteristics and low noise, with a maximum MHz rate of 10. This makes it ideal for use in modern digital systems.

Tantalum capacitors exhibit superior long-term stability, making them well suited for applications requiring long term reliability. Additionally, the ability of tantalum capacitors to withstand high temperatures makes them ideal for applications in high-temperature environments. Furthermore, their low leakage current and virtually indefinite shelf life make them attractive for use in medical and aerospace applications.

In summary, the T491B105M035AG tantalum capacitor is a versatile, reliable, high performance component ideal for a variety of filter, decoupling, buffering and bypass applications. It incorporates a low ESR, high capacitance and low leakage current, resulting in a long service life even under extreme environmental conditions. Furthermore, its small size makes it ideal for use in portable electronic devices and high temperature environments, while its excellent high frequency characteristics make it well suited for modern digital systems.
