Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are one of the most commonly used capacitors available. They are a type of polarized capacitor made out of an anode consisting of aluminum and a cathode consisting of paper and metal foil. An AEC is composed of two distinct metal foils insulated by a thin layer of oxide film. An electrolyte is used to form a bridge between the anode and cathode, allowing electric current to flow through the capacitor.

The ESMQ201VSN391MP25S is an AEC with an rated capacitance of 2.0uF and a rated voltage of 25V. It is a highly popular, general purpose aluminum electrolytic capacitor used for a wide variety of applications. It is used in low to medium power circuits that require stable capacitor voltage. It is also often used in automotive electronics, where it is used to regulate current and smoothen out voltage spikes.

Working Principle

AECs work by storing electrical energy with the help of the oxide layer between the two metal foils. The oxide layer acts as a dielectric material and has a specific distance between it and the two electrodes, which prevents current leakage between the two. The electrical charge is stored in the oxide layer, creating an electric field between the two electrodes.

When the capacitor is charged, the electric field between the two electrodes increases until it reaches its maximum value. This creates a strong electrostatic field capable of storing electrical energy for a specified amount of time. When the capacitor is discharged, the electric field between the two electrodes decreases until it reaches its minimum value, releasing the stored energy.
