Introduction

T491C476K016ZT7280 is a kind of surface mount capacitor which is often used in many applications, such as automotive and industrial processes. The capacitor is a few millimeters thick and is typically available in a range from 0.5 to 10 μF capacitance. It is made of tantalum, a material that is highly popular for its heat resistivity, mechanical strength, and chemical inertness.

Applications 

T491C476K016ZT7280 is a great choice for many applications in the aerospace, automotive and industrial areas. It is a reliable, long-lasting and cost-effective option for smoothing pulse-varying signals and energy storage applications. The considerably high capacitance of the T491C476K016ZT7280 allows it to readily handle the large capacitance requirements necessary in electronic filter circuits, power supplies and voltage regulators.

Moreover, its temperature characteristics and various other electrical characteristics make it ideal for timing/delay circuits, data converters and frequency synthesizers. It also proves to be useful in several consumer electronic appliances such as tablets, cell phones, etc.

Working Principle

T491C476K016ZT7280 consists of two identical parallel plates each with a layer of dielectric film placed between them. The plate arrangement is put in a metallic container. A single layer of tantalum is deposited onto the plate by a special process, followed by an anode foil, in which a metallic-oxide is deposited. As voltage is applied to the capacitor, both plates charge up. Thus, the electrons become polarized. The capacitor then acts as a current limiter and a resistor as far as pulsed current is concerned. The charge stored on the plates is given by the equation Q = C x V, where Q represents the charge stored, C is the capacitance and V is the voltage.

The capacitance of the capacitor is primarily determined by two factors – the size, shape, and materials of the plates; and the dielectric constant, or the ability of the dielectric film to store electrical field energy.

Conclusion

T491C476K016ZT7280 is a tantalum capacitor with a very high capacitance of 0.5 to 10 μF. It is very reliable, enduring, and cost effective due to its temperature characteristics and other electrical characteristics. The T491C476K016ZT7280 is used in many automotive and industrial applications, as well as consumer electronic appliances such as tablets and cell phones. Its working principle is based on two identical parallel plates, with a layer of dielectric film between them, which store a charge on the plates when voltage is applied. This makes it highly useful for applications that require a large capacitance.
