Another application for the T491C685K020AS is in high-quality audio systems, as its excellent dielectric properties help to reduce sound distortion. The capacitor is also used in military and industrial applications as well, due to its ability to withstand extreme operating conditions.

In order to understand how the T491C685K020AS works, it is important to recognize that it is a polar capacitor. This means that it has two electrode leads, with the positive lead being the anode and the negative lead being the cathode. When an electric current is applied to the capacitor, positive ions are attracted to the negative electrode, while negative ions are attracted to the positive electrode. This creates an electrostatic field between the two electrodes, and this field is what is responsible for storing the charge within the capacitor.

The T491C685K020AS also has a low equivalent series resistance (ESR) and a low impedance, which makes it useful for applications that require high frequency circuit components. Its low ESR helps to decrease the heat generated by the capacitor, allowing it to work efficiently under extreme conditions. Additionally, its low impedance helps to reduce interference with other components in the same circuit.

In conclusion, the T491C685K020AS is a precision grade miniature surface-mounted miniature capacitor with an oxygen dipped anode. It is made of tantalum and uses an anodised silica dioxide layer as its dielectric, and it is available in various sizes with a capacitance that ranges from 0.47μF to 680μF, and a voltage rating of between 6.3VDC and 50 VDC. The T491C685K020AS is used in a variety of high-end electronics applications due to its ability to handle extreme operating conditions, its low equivalent series resistance,and its low impedance. Its features make it an ideal choice for applications requiring a reliable and long-lasting component.
