Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, or simply electrolytic capacitors, are polarized capacitors that contain an anode made of aluminum foil and use an electrolyte to draw electric current, with their inherent advantages including large capacitance, low cost, small size, and light weight.

B41888C8566M000 Application Field

The B41888C8566M000 is an aluminum electrolytic capacitor used in various industries and applications. It is primarily used in equipment requiring high-energy levels, such as DC blocking, inrush current resistors, snubbers, and transient suppressors. In addition, it can be used in combination with other compounds to form ceramic capacitors, as well as for EMI/RFI protection and suppression. Its operating temperature range is -40°C to 85°C.

Working Principle of B41888C8566M000

The B41888C8566M000 is composed of two plates separated by an electrolyte. When a voltage is applied to the capacitor, a current flows through the electrolyte and plates, allowing charge to accumulates on the plates. The amount of charge accumulated depends on the capacitance of the capacitor, which is determined by the area of the plates and the distance between them. The current flow through the electrolyte also causes oxidation of the anode, which increases the capacitance with time.

The capacitor generates a voltage drop due to the resistance of the electrolyte, which reduces the total charge accumulated on the two plates. This effect is termed as the electrolytic leakage and is generally observed in all electrolytic capacitors at higher temperatures. The capacitance of the B41888C8566M000 increases with increasing temperatures, due to increased charge flow through the electrolyte, but is limited by the electrolytic leakage.
