Aluminum electrolytic capacitors are widely used in various electronic devices, from phones to computers, amplifiers or cameras. Especially 420MXG82MEFC20X25 application field is mainly applied to power supply circuits, such as domestic appliances, consumer electronics, lighting fixtures, automotive and industrial applications.

The working principle of aluminum electrolytic capacitors is based on Faraday’s law of electrolysis. A thin aluminum foil sheeting is rolled together with specially treated paper soaked in electrolyte and an anode is separated by a separator. The anode and the cathode are rolled together, and then inserted into an aluminum can with a lid.

When the voltage is applied, aluminum oxide, which is an insulator, forms on the aluminum foil surface. The oxide layer insulates the aluminum from current, thus creating negative electrodes on the surface of the aluminum and divided capacitance. This creates a large electrolytic capacitor that can hold more charge than a regular capacitor.

The aluminum can of the 420MXG82MEFC20X25 aluminum electrolytic capacitor is molded in a radial shape with an anode, a cathode, and a leadwire for electrical connection. The inside construction serves as the dielectric medium, which is made of an electrolyte. This electrolyte is stabilized with a special additive that minimizes the change rate of leakage current over a long period of time.

The 420MXG82MEFC20X25 aluminum electrolytic capacitor is held in place by conducting solder on the anode terminal. The other end is held in place by a plastic stopper, which prevents the electrolyte from spilling in case of a thermal overload. The contacts in the device are designed to withstand currents up to 30 amperes.

In summary, the 420MXG82MEFC20X25 aluminum electrolytic capacitor is an ideal choice for applications where large currents are needed, such as automotive and industrial applications. It is a reliable and durable device, with a long life span and excellent performance. It is also suitable for any application where extended operating life is desired.
