Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses an electrolyte of aluminum oxide forming a thin layer on an aluminum plate, as the dielectric, and thin metal foil as the electrodes. This creates an electrolyte/electrolyte interface as the capacitive element between them, resulting in high capacitance.

Application Field of B41858C7108M000

The B41858C7108M000 aluminum electrolytic capacitor is widely used in high-frequency switching power supplies, active power factor correction circuits, and high-earphone drive. Additionally, it can be used in a variety of automotive, industrial and consumer products such as televisions, car navigation systems, motor control, lighting, variable speed drives, computers, robots and audio electronics.

Working Principle

The principle of operation for an aluminum electrolytic capacitor is based on current flow through an electrolyte and a metal plate. The current flow causes a reaction to occur in the electrolyte, and, as a result, a thin layer of aluminum oxide forms on the metal plate. This forms the dielectric, or insulating layer between the electrodes. These two electrodes form the capacitor and the size of the capacitor depends on the area of the plates and the dielectric thickness.

The capacitance of the capacitor is determined by the area of the electrodes and the thickness of the dielectric. As the amount of charge increases, the dielectric intensifies, which in turn reduces the capacitance of the capacitor. The capacitance of the B41858C7108M000 is 1000uF, which means that it can store a maximum of 1000uF of charge.

Aluminum electrolytic capacitors have a relatively high rated ripple current, ensuring dependable operation in the presence of high frequency disturbances, such as motor noise and switching power supplies. The maximum ripple current for the B41858C7108M000 is 5.5A, which indicates that it can handle high currents without experiencing any negative effects.
