Working Principle

A tantalum capacitor is made of two pieces of metal foil separated by a layer of tantalum pentoxide (Ta2O5). The metal layers of the capacitor act as \'plates\', while the tantalum pentoxide acts as the dielectric layer bewteen them. When the capacitor is connected to an electrical circuit, it accumulates electrical charge.Within the capacitor, the positive plate stores incoming positive charges, while the negative plate stores negative charges. As the capacitor starts to fill up with electrical charge, it creates a capacitor voltage which builds up to the capacitor\'s maximum voltage rating. The amount of charge that the capacitor stores is determined by the capacitance of the capacitor, which is measured in Farads. The capacitance depends on the size and type of capacitor, as well as its dielectric constant. When the capacitor is connected to the power source, current will start flowing through it, allowing the capacitor to slowly fill up. As the capacitor starts storing electrical charge, it will start to act as a filter, blocking high frequency signals from passing through the circuit. As a result, the signal that passes through the capacitor will only be the DC signal, allowing a stable and accurate signal to be transmitted.T491C476K016AT tantalum capacitor is designed for long-term reliability, allowing it to deliver stable performance for long period of time. The capacitor also provides good temperature cycling stability, which is essential in extreme environmental applications.
