Introduction to Tantalum Capacitors

Tantalum capacitors are part of the electrolytic family of capacitors, which consists of devices that use an electrolyte combined with a metallic material as the dielectric. They are also known as wet capacitors, because they contain a metallic material, as well as a liquid (the electrolyte) in order to store electrical charge. Tantalum capacitors are very popular components and are used in a wide variety of electronic devices; they are commonly found in digital circuitry such as computers, TVs, cell phones, and other consumer electronics.

T491C106M016AS Application Field and Working Principle

T491C106M016AS, manufactured by KEMET, is a surface mount tantalum-polymer capacitor. It has an operating temperature range of -55°C to 125°C, a voltage rating of 6.3V, and a capacitance of 16µF. The T491C106M016AS is a very common type of capacitor used in a variety of electronics, such as mobile phones, computer motherboards, and audio equipment.The T491C106M016AS is a double-layer capacitor, meaning that it consists of two layers of dielectric material that act as insulators separating two conducting electrodes. The dielectric material is comprised of an electrolyte and a thin film of tantalum. The electrolyte is a solution of potassium hydroxide (KOH) that is saturated with dissolved oxygen, while the tantalum metal is an impregnated powder that serves as the second layer of dielectric material.When a voltage is applied to the terminals of the capacitor, negatively charged potassium ions move towards the positively charged tantalum layer, while positively charged oxygen ions move to the negatively charged tantalum layer. This causes the two layers to become electrically charged, creating an electric field between them. The electric field created by the electric field produces an electrostatic force, which attracts positively charged electrostatic particles onto the surface of the tantalum layer. This electrostatic charge is stored in the capacitor until the voltage across the capacitor decreases.The T491C106M016AS has excellent temperature stability and a low equivalent series resistance (ESR). It is also very reliable and can withstand multiple over voltage cycles without damage. The T491C106M016AS is also an ideal capacitor for high-frequency applications, such as cellular phones and audio amplifiers.

Conclusion

The T491C106M016AS is a reliable and high-performance electrolytic capacitor that is used in a variety of electronic devices. It has excellent temperature stability, low ESR, and can withstand multiple over voltage cycles, making it an ideal capacitor for high-frequency applications.
