T491C226M010ZT is a surface-mount tantalum capacitor with an octagonal outline. The T491C226M010ZT offers high capacitance in the tiny 0805 package, and it has a high volumetric efficiency, making it an ideal choice for applications that require small size but high capacitance.

Tantalum capacitors are components that store electrical energy in an electric field. These capacitors are made of a metallic tantalum material, an element from the periodic table. This type of capacitor has a very high capacitance-to-volume ratio, making it a favorite for miniature designs. Tantalum capacitors are also known for their high stability, low leakage current, and their ability to handle high operating temperatures.

Applications of the T491C226M010ZT tantalum capacitor include DC-DC converters, power supplies, and power management. This component also finds use in automotive electronics, medical electronics, and military and aerospace applications. It is a versatile part that performs well in such applications.

The working principle of a tantalum capacitor is based on the principle of electrostatic capacitance. A layer of tantalum pentoxide formed between two layers of tantalum material forms the dielectric layer. This property allows the capacitor to store energy when voltage is applied, creating a barrier through which current cannot flow. When the capacitor is discharged, it releases the stored energy, allowing current to flow through it.

In a T491C226M010ZT, the two layers of tantalum metal are connected by a solid-state electrolyte that forms a double-layer of the oxide on the surface of the metal. This gives the capacitor a high volumetric efficiency, allowing it to store a large amount of energy in a small form factor. This process also makes the capacitor more resistant to corrosion and leakage than standard polymer-based capacitors.

The T491C226M010ZT is just one example of a tantalum capacitor, but its design is a good example of how these components are used in many high-tech applications. Its high volumetric efficiency and stability make it an ideal choice for miniature and demanding designs. Tantalum capacitors are also highly resistant to corrosion and leakage currents, making them ideal for applications requiring robust performance.
