Aluminum electrolytic capacitors are among the most common passive components used today. They are used in a variety of electrical and electronic applications, and can be found in products ranging from everyday household items to highly specialized medical devices. The MAL202190547E3 is a type of aluminum electrolytic capacitor, and its application field and working principle are described below.
Application
The MAL202190547E3 is a medium-sized aluminum electrolytic capacitor which is used mainly for computing power supplies, rectifying circuits and signal banks. Its wide operating temperature range, low ESR and capacitance range makes it suitable for use in a variety of applications. Its small size and low cost makes it a good choice for applications which require a large number of capacitors or for high-volume manufacturing.
Working Principle
The working principle of an aluminum electrolytic capacitor is based on the charge storing properties of the aluminum oxide layer which forms a dielectric between two parallel plates. A positive charge is stored on one plate and a negative charge is stored on the other plate. When the potential between the two plates is greater than the potential of the dielectric layer, a current will flow through the capacitor, thus storing an electrical charge which can be used later in the circuit.
The MAL202190547E3 capacitor is constructed with two aluminum plates coated with a thin layer of anodic oxide. When a voltage is applied to the plates, a thin layer of anodic oxide forms an insulating barrier between the two plates. This barrier prevents the electric charge on the plates from leaving the capacitor, which increases the capacitance and allows the capacitor to store more charge. The anodic oxide layer acts to reduce the electrical leakage between the plates and increases the operational life of the capacitor.
Conclusion
The MAL202190547E3 aluminum electrolytic capacitor is a versatile and reliable component which can be used in a variety of applications. Its wide operating temperature range, low ESR and capacitance range make it an ideal choice for applications requiring a large number of capacitors or for high-volume manufacturing. Its working principle is based on the charge storing properties of the aluminum oxide layer which forms a dielectric between two parallel plates.
