Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are devices used for energy storage and pulse supply in a wide range of electronic applications. Compared to other types of capacitors such as ceramic capacitors, aluminum electrolytic capacitors have higher capacitances and can provide much higher current. This type of capacitor consists of an anode made of aluminum foil, an electrolyte containing mainly ions of aluminum oxide, and a cathode made of aluminum foil.

The model of B41458B5220M003 is an aluminum electrolytic capacitor usually used for smoothing application in power supplies, or as a part of a voltage regulation system in industrial applications. It features a capacitance of 2200 μF, a rated voltage of 25V and an operating temperature range from -40°C to +85°C.

Working Principle

The working principle of B41458B5220M003 is in line with other types of aluminum electrolytic capacitors. Its operation is based on the principle of electrochemical oxidation of aluminum anode, which creates an oxide film full of holes or pin holes. The anode subsequently dissolves, forming a number of small aluminum surfaces which are the source of the capacitor\'s large capacitance. The current supplied to these small surfaces constitutes the voltage-dependent charge discharged during operation.

When an electric current is applied to the capacitor, positive ions of the electrolyte in the anode\'s oxide film move towards the cathode while negative ions of the electrolyte in the anode\'s oxide film move towards the anode. The energy stored in the capacitor is then discharged, leading to a voltage drop and current flowing towards the cathode. This energy is then released as a result of a decrease in the capacitance due to electric field reversal.

Application Field

B41458B5220M003 is primarily used for smoothing application in power supplies, in computer systems as well as in automotive, telecommunication and industrial applications. Its capacitance of 2200 μF and relatively large operational temperature range make it suitable for a wide range of applications.
