The aluminum electrolytic capacitor

The Aluminum Electrolytic Capacitor is a type of capacitor that uses aluminum as the anode in an electrolyte, and a metal film as the cathode. It is a passive electrical component that is used to store energy. The Aluminum Electrolytic Capacitor is widely used in AC power conversion, power electronics, and data processing applications due to its excellent electrical properties such as high capacitance, low equivalent series resistance (ESR), and low parasitic inductance.

E36D400LPN403UCA5M application field

The E36D400LPN403UCA5M type of Aluminum Electrolytic Capacitor is a high-temperature, high-voltage capacitor. It is generally used in switching power supplies, UPS power supplies, and other applications that require high-voltage operation and high environmental temperatures. This type of capacitor is also used in motor drives, LED lighting, medical and other critical components that require high reliability.

The E36D400LPN403UCA5M capacitor offers low ESR and high capacitance ratings, making it especially suitable for noise and ripple suppression. It also has superior electrical characteristics, such as low equivalent series resistance (ESR).

Working Principle of the Aluminum Electrolytic Capacitor

The working principle of an Aluminum Electrolytic Capacitor is based on Faraday’s laws of electrolysis. The laws state that when a voltage is applied to an electrolyte a current will flow between two electrodes placed in the electrolyte. The current flow causes the anode (positive electrode) to oxidize, and the cathode (negative electrode) to reduce. This electrochemical reaction creates a capacitance of the Aluminum Electrolytic Capacitor.

The capacitance of an Aluminum Electrolytic Capacitor is determined by its design and the material used to construct it. The capacitance of a typical Aluminum Electrolytic Capacitor increases with its operating voltage and dielectric (insulating) material. This is why two Aluminum Electrolytic Capacitors with the same size and construction can deliver vastly different capacitance when operated at different voltages.

The most common application of Aluminum Electrolytic Capacitors is noise and ripple suppression in switching power supplies which require high capacitance and low ESR. Aluminum Electrolytic Capacitors are also used as decoupling capacitors in audio circuits, power supplies, and other applications. They are also used as resonance capacitors for filtering, tuning circuits, and resonance suppression.
