ELXM451VSN121MP45S

ELXM451VSN121MP45S is an aluminum electrolytic capacitor, which mainly consists of an aluminum foil sandwiched between two layers of metallized paper, with a liquid electrolyte as the dielectric material. It is an electrical component used to store electrical energy after charging and to pass an alternating current within the same direction as the charging current. It is a necessary component in electronic circuits and is capable of delivering a large amount of static charge in a brief period.

ELXM451VSN121MP45S capacitors are widely used in currents like 100µA and upwards. It can bear a voltage up to 450V and is mostly used in applications such as in DC blocking circuits, note taking circuits, AC coupling, filter circuits, coupling circuits, suppression circuits, feedback circuits, power supply bypass circuits, motor drive circuits and high-frequency circuits.

When power is applied, the positive and negative terminals of the capacitor are polarized, with the positive terminal being the anode and the negative being the cathode. During the process of charging, the positive current passes from the anode to the cathode through a liquid electrolyte and this reverse direction creates an electrical field between them. As the electric field accumulates, it releases electrons from the positive terminal to the negative terminal which results in the accumulation of charge on the plates of the capacitor. As a result, the capacitance of the device is increased temporarily until it is able to complete the charging cycle.
