Aluminum Electrolytic Capacitors

180VXR680MEFC22X45 application field and working principle

Aluminum electrolytic capacitors are electro-chemical components used to store electrical charge, and are widely used in consumer electronics and commercial electronics devices. Aluminum electrolytic capacitors are composed of four major components: positive and negative plates, electrolyte and sealed cases. The anode of the aluminum electrolytic capacitor is made of pure aluminum foil with many etchings on the surface. A thin layer of aluminum oxide is formed on the anode surface during electrolysis, and acts as the dielectric. The cathode is generally made of plain metal and provides electrons to the circuit. The electrolyte acts as the third component, and is such as ethylene glycol, combined with organic acids. Most aluminum electrolytic capacitors are sealed with cases made of plastic, rubber or glass.

The 180VXR680MEFC22X45 aluminum electrolytic capacitors are radial leaded angle aluminum electrolytic capacitors with capacitance values ranging from 2.2μF to 47μF and rated voltage from 6.3V to 200V. These capacitors are capable of operating between -40 °C to +85 °C. The 180VXR680MEFC22X45 features a high temperature, low impedance, thickest electrolyte and extended shelf life. The anode surface is pre-coated with anodic material which ensures high reliability and stability.

The 180VXR680MEFC22X45 aluminum electrolytic capacitors have a wide application scope. They are mainly used in electrical power systems, switching power supplies, lamps and lanterns, industry electric equipment and motors. They can also be used in RC filters, noise filters, DC-DC converters and other components. Furthermore, they are suitable for automotive electronics, telecommunications, computers, consumer electronics and other digital systems.

The working principle of aluminum electrolytic capacitors is based on an electrochemical reaction. This reaction is used to create an electric field across the capacitor and allow current to flow through the plates. The two plates are separated by an insulating layer called the dielectric. The dielectric is electro-chemically formed and can withstand the large voltages and currents produced by the electrolytic reaction.

The electrolyte, a solution of water and acid, provides the ions required for the electrolytic reaction to occur. When a voltage is applied to the plates, the electrolyte ions are attracted to the negative plate and away from the positive plate creating an electric field. This electric field creates an electrochemical reaction, which charges the plates. This creates an electric field with opposite polarity to the initial voltage applied. The charged plates store electrical energy and are discharged when the voltage drops.

In summary, the 180VXR680MEFC22X45 aluminum electrolytic capacitors have a wide range of applications and feature high capacitance values with extended shelf life. They work based on the principle of an electrochemical reaction and are capable of withstanding large currents and voltages. These capacitors are used in various electrical power systems, switching power supplies, lamps and lanterns, industry electric equipment, motors, RC filters, noise filters and DC-DC converters.
