Tantalum Capacitors

A tantalum capacitor is an electronic component composed of a powder made from an alloy of tantalum and an electrolyte. It functions as a capacitor, similar to other non-polarized electrolytic capacitors. Tantalum capacitors provide the advantage of a higher capacitance per unit volume compared to other types of capacitors; however, they are more expensive and can cause greater over-voltage problems than other types of capacitors.

T491T226K010AT Application Field and Working Principle

The T491T226K010AT is a surface-mount oriented tantalum capacitor used mainly in high power applications. Its applications span across a wide range of electronic devices including digital logic circuits, computers, etc. Its operating temperature is between -55°C and +125°C.

The working principle of the T491T226K010AT tantalum capacitor is based on the dielectric layer that is formed between two layers of tantalum powder and electrolytic solution. The two layers of tantalum powder prevent the electrolytic solution from passing electricity. The electrolytic solution helps to maintain an electric potential between both layers. This potential creates a capacitance that can be used to store electrical energy.

The T491T226K010AT has a low equivalent series resistance (ESR). This helps reduce the amount of heat generated during charge and discharge. This also helps reduce the size of the capacitor as it can be made smaller than conventional types. Furthermore, the low ESR makes the T491T226K010AT a suitable choice for applications that require high-speed switching and high performance.

The T491T226K010AT also offers high reliability and durability. With its low impedance and high current capability, the T491T226K010AT is capable of withstanding surge currents and voltage spikes. This makes it a good choice for use with power supplies and high-current applications. Furthermore, the capacitor\'s low leakage current helps minimize the risk of connection failure.

Another advantage of the T491T226K010AT is its low ESR temperature coefficient, which reduces the output changes caused by the change in the temperature of the capacitor. This makes the T491T226K010AT ideal for applications that require a stable voltage output in a wide range of temperatures.

In conclusion, the T491T226K010AT is a highly reliable and durable surface-mount oriented tantalum capacitor that is used mainly in high-power applications. It offers low ESR, high reliability and low leakage current. Furthermore, its low ESR temperature coefficient helps reduce output changes caused by temperature changes.
