Working Principle of T491B157M004AT4280 Tantalum Capacitors

T491B157M004AT4280 Tantalum capacitors are made up of a tantalum anode (positive electrode) and a metal oxide cathode (negative electrode). The anode is generally made of a thin sheet of tantalum metal oxide, surrounded by a protective layer of MnO2. The cathode is usually made of a thin layer of manganese dioxide, although other metal oxides can be used. The two electrodes are then submerged in an electrolyte solution.

When the device is connected to an electrical source, such as a battery, current flows from the positive to the negative terminal. This creates an electric field that causes electrons to move from the anode to the cathode, creating a charge between the two electrodes. The capacitance of the device is determined by the amount of charge stored between the two electrodes.

The unique construction of the T491B157M004AT4280 Tantalum capacitors gives them several advantages over other types of capacitors. The device has a low ESR (equivalent series resistance), which allows it to handle high frequency signals more efficiently.
