T491B475K020AT4081

T491B475K020AT4081 is a type of tantalum capacitor, which plays an important role in electronics. Tantalum capacitors are one of the most common types of capacitor and have a tremendous range of applications, including amplified audio/visual playback and signal clean-up. A tantalum capacitor is a dry-electrolytic capacitor consisting of a tantalum metal working electrode, an oxide layer and an electrolyte of tantalum pentoxide. They are small and are used in mobile phones and other portable electronic devices.

The T491B475K020AT4081 is a three-lead, axial-leaded, surface-mount type of capacitor that is used in a wide range of applications. Its rated voltage is 40V, with a capacitance range of 2-300uF. It is suitable for a wide range of frequencies and features excellent moisture resistance, electrical stability, and low-ESR (Equivalent Series Resistance). This capacitor has a wide temperature range operating between -25°C and 85°C.

The main application field of the T491B475K020AT4081 capacitor is as a bypass capacitor. Bypass capacitors are typically used in power supplies, high-frequency circuitry, and other applications that require low-ESR and slow transients. Bypass capacitors reduce the peak current and provide filtering for low-frequency noise. They are also used for improving the power output of amplifiers and for the protection of the electronics from radio-frequency interference (RFI).

The working principle of the T491B475K020AT4081 capacitor is based on the fundamental law of electricity, which states that the electric current is always conserved. All currents leaving one point of a circuit must also go into another. The capacitor works to store the charge and as a link between the two points, providing a connection paths between them, allowing the current to flow either one way or both ways. The capacitance of a capacitor is measured in Farads and it is directly proportional to the surface area of the electrodes. When a capacitor is connected to a power source, it creates an electric field and a dielectric effect. This creates an accumulation of potential energy and the capacitor stores that energy until the electric field dissipates.
