Working Principle of T491B157M006AT4100

T491B157M006AT4100 is a kind of Tantalum capacitor, which is electrochemical in nature. It is composed of a solid electrolyte made from Tantalum pentoxide and a conductive polymeric material. This polymeric material is usually activated carbon that is conductive. The capacitor stores energy in the form of an electrostatic field between the anode (positive electrode) and the cathode (negative electrode).

When an electric current passes through the solid electrolyte, it is then stored in the capacitor. The current passes through the conductive material and into the electrolyte where it is stored. This stored energy can then be used when the capacitor is required to discharge.

The capacitance value of the T491B157M006AT4100 is determined by the amount of surface area of the anode and cathode, the type of electrolyte used and its thickness. The capacitance value of the T491B157M006AT4100 is typically in the range of 100 μF to 10 mF.

T491B157M006AT4100 capacitors have a long life span and are highly reliable and resistant to thermal cycling and ripple current fatigue. They are also resistant to vibration, shock and mechanical stress.
