T491D336K035AT7027 is one of the Tantalum capacitors, and is a form of small electrolytic capacitor. The sample models of this particular capacitor include a variety of shapes, such as chips, epoxies, and axials, depending on the specific application. This capacitor has a polarity, as well as very high capacitance in a very small, lightweight, and reliable package. It is typically used in a variety of low voltage, high frequency, and/or space restricted applications, and has been established as one of the best types of capacitor for these applications.

In terms of application field, Tantalum capacitors are mainly used to provide very low-frequency filtering or decoupling, as well as to reduce transient noise, such as from electronic switching. These capacitors are also widely used in power supply applications, such as direct current (DC) and alternating current (AC). For DC applications, because of the relatively high capacitance rating available with Tantalum capacitors, they are usually employed as filtering devices.

In terms of working principle, Tantalum capacitors are constructed through the combination of tantalum and dielectric materials; it works by storing energy in the form of an electrostatic field. When the capacitor is in use, positive charges are stored in one plate, whereas negative charges are stored in the other. The electrical field that is generated between these plates is what enables the capacitor to store the energy. When a voltage is applied to the capacitor, charges flow to both plates—in opposite directions, and this causes the capacitor to store the energy.

Tantalum capacitors are also often used as bypass or decoupling capacitors, because of their ability to quickly respond to changes in voltage. When a rapid change occurs, these capacitors divert charge to the affected areas, thus preventing high voltages. They are also usually used in power supply circuits, in general, due to their capacitor-like properties and their ability to filter high volatge AC signals.

The T491D336K035AT7027 is an excellent choice of capacitor for applications where high frequency and high-level, transient noise-filtering is essential - such as in computers, embedded systems, and telecommunications devices. It also features a high capacitance rating (3.3uF) and low ESR rating (70mOhm), and can be used in a wide range of temperatures (-55C to + 125C).
