Aluminum electrolytic capacitors, also known as “wet” or “aluminum can” capacitors, are widely used in all kinds of electronic circuits. A typical aluminum electrolytic capacitor consists of two aluminum plates, one a solid foil and the other a porous oxide layer, which is etched and wound into a cylindrical shape. The outer and inner surfaces of the capacitor are usually metallized to ensure electrical contact between the lead wires and the plates. The aluminum capacitor is polarized and has a voltage rating up to several hundreds of volts.

The capacitor is then filled with a water-based electrolyte, which acts as a dielectric medium. This electrolyte, typically a mixture of borates, nitrates and sulfates, enables the capacitor to store an electrical charge. In addition, the electrolyte also aids in the formation of the oxide layer on the electrode, providing the electrical insulation necessary for the capacitor to operate reliably.

420QXW180MEFC18X40 is an aluminum electrolytic capacitor with an extremely high energy density and excellent stability. It offers a wide operating temperature range from -40°C to +85°C and is designed to operate in harsh environments. The capacitor is available in multiple sizes and is suitable for automotive, high-powered electronics and industrial control applications, including power conditioning, electric vehicle motors, instrumentation, machine tools, and robotics.

The working principle of the 420QXW180MEFC18X40 aluminum electrolytic capacitor is essentially the same as that of any other capacitor. When an electric field is applied, it stores energy in the form of an electrical charge on its plates. As voltage is applied across the plates, current will flow from the plates, generating heat. The heat generated will ultimately cause the capacitor’s electrolysis to break down, resulting in corrosion. The electrolyte, in combination with the plate, can create a charge that is stored in the device until a voltage is applied.

420QXW180MEFC18X40 aluminum electrolytic capacitors have been designed to operate in extreme temperature settings, as well as high vibration and shock environments. The capacitors are capable of storing and releasing high amounts of energy and are able to handle large inrush currents, making them a reliable and efficient choice in applications that require energy storage and power regulation. In addition, the capacitors offer excellent cycle life performance, which ensures that they are long lasting and reliable.
