Working Principle

T491B684M050AT capacitors work with the same basic principle as other capacitors. A capacitor, in essence, is an electronic device that stores energy in an electric field created between two conductive plates. The more plates it has and the larger they are, the more energy it can store. The T491B684M050AT has two plates (one positive, one negative), with the plates constructed out of tantalum, allowing it to store a large amount of charge in a small package.

When voltage is applied to the capacitor, the positive plate is charged while the negative plate is grounded, creating the electric field. The capacitance of the capacitor is determined by its size and the material of the plates; the larger the surface area of the plates or the higher the dielectric constant of the material, the higher its capacitance. The T491B684M050AT capacitor has a capacitance of 684 microfarads, in a small, surface-mount package.

Due to its small form factor and its ability to handle high voltages, the T491B684M050AT capacitor is well-suited for a variety of applications. From active filters to noise suppressors and AC coupling circuits, it is a versatile and reliable capacitor that can be used in a wide range of designs.
