Aluminum electrolytic capacitors are designed to offer high capacitance values in the smallest possible packages at a fraction of the cost of other electrolytic capacitors. They use a chemical reaction of anodic oxide and a metal alloy to store and control electrical current. By controlling this current, they can provide ideal timing, damping, and filtering functions in a variety of electronic and mechanical systems.
E81D350VEN472MR25W aluminum electrolytic capacitor is a type of non-polarized, radial-leaded, screw terminal aluminum capacitor which contains a non-electrolytic anodic oxide layer made of aluminium oxide on the positive electrode. The anodic oxide layer of the capacitor will form insoluble anode when the electrolyte reacts with the electrode. The capacitor has a capacitance of 81µF, a voltage rating of 350V DC, a lead length of 2.7mm, a terminal diameter of 2.5mm, a lead including solder post length of 12.7mm and it’s working temperature range is from -55°C to +85°C.

This aluminum electrolytic capacitor technology offers improved performance, lower volumetric efficiency and higher ripple current compared to other types of capacitors. Their physical properties are ideal for applications such as radio-frequency (RF) energy storage, power-supply smoothing, audio-system decoupling and high-voltage filtering. They offer a wide range of characteristics to suit the needs of different applications.

The general working principle of E81D350VEN472MR25W aluminum electrolytic capacitor is that it stores electrical energy by using a dielectric between two metal plates, forming a capacitor. The positive plate (anode) is made of aluminum foil and the negative plate (cathode) is made of an aluminum oxide dielectric layer. When electric current is applied to the anode and the electrolytic gel, a conducting layer grows on the anode of the capacitor, forming a capacitor with two metal plates separated by a dielectric.
The operation of the capacitor is based on Faraday’s Law, which states that the amount of energy stored in a capacitor is proportional to the quantity of charge stored on its two plates. When the capacitor is connected in a circuit, electrons flow from the anode to the electrolytic gel, creating an electric charge. This charge attracts particles from the electrolytic gel to the anode, forming a capacitor. The layer of electrolyte gel acts as a dielectric between the anode and cathode, separating the two. As the capacitor is charged, the electric field created between the two plates stores energy.

E81D350VEN472MR25W aluminum electrolytic capacitor is commonly used in applications such as tuned circuits, timers, oscillators and pulse-width modulation (PWM) circuits, where they provide the accuracy and reliability needed to improve performance and minimize energy losses. Additionally, they are perfect for filtering high-frequency noise and filtering signals in low-frequency circuits. Some applications also include DC servo motors, solenoids and relays, switch mode power supplies, audio power amplifiers, inverters and circuits for protecting against lightning.

In conclusion, E81D350VEN472MR25W aluminum electrolytic capacitor is an ideal choice for many electrical and electronic applications that require high reliability, high capacitance, and low cost. Its features include low ESR, low ESL, DC isolation, corrosion resistance, low leakage current, and high voltage rating.
