Tantalum Capacitors

Tantalum capacitors are electronic components that use a polymerized tantalum compound as its electrolyte, rather than a liquid liquid electrolyte, to store energy electrostatically. They are characterized by their small size, high capacitance values, wide range of operating temperatures, long shelf life, low leakage current, low self-discharge rate, and good reliability.T491A107M004AS is a type of tantalum capacitor. It is a high-performance, low-profile, lead-free, AEC-Q200 qualified, surface mount electrolytic capacitors. It has a capacitance of 10uF and a voltage of 4V. It is designed to provide a reliable capacitive energy storage solution suitable for a range of applications, such as automotive, consumer, and medical electronics.The working principle of the T491A107M004AS is relatively simple. It utilizes two concentric layers of a solid dielectric material, such as tantalum pentoxide, which are sandwiched between two electrical connections, or electrodes. The application of a voltage across these electrodes creates an electric field, which causes the capacitance of the system to increase or decrease according to the strength of the applied voltage. This change in capacitance allows for the storage of electrical energy in the form of an electrical charge.The T491A107M004AS is suitable for a wide range of applications, such as automotive, consumer, and medical electronics. In automotive electronics, it can be used for DC-DC converters, battery charging systems, voltage regulators, and electronic control units. In consumer electronics, it is used for power supplies, DVD players, video game consoles, MP3 players, and other electronic components. In medical electronics, it is used in pacemakers, hearing aids, insulin pumps, and other medical devices.Tantalum capacitors, such as the T491A107M004AS, offer many advantages compared to other types of capacitors. They are smaller and lighter than aluminum electrolytic capacitors, have a longer operational life, and are more reliable. Additionally, these capacitors have a self-healing effect, meaning that if an excessive current passes through the capacitor, the current is limited and it does not cause permanent damage to the device.In conclusion, the T491A107M004AS is a high-performance, low-profile, lead-free, AEC-Q200 qualified, surface mount tantalum capacitor. It has a capacitance of 10uF and a voltage of 4V. This capacitor is suitable for a wide range of applications, including automotive, consumer, and medical electronics. It offers many advantages, such as a long operational life, reliability, and a self-healing effect.
