Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, sometimes referred to as electrolytic film capacitors, are widely used in electronic equipment, computers, communications, automotive electronics and other fields. The 420KXW82MEFC18X25 is an aluminum electrolytic capacitor designed to fit today’s most demanding applications. This article will provide an overview of this specific part number and how it fits into the aluminum electrolytic capacitor category.

What is an Aluminum Electrolytic Capacitor?

An aluminum electrolytic capacitor is a type of electrolytic capacitor that utilizes aluminum foil as a cathode and a separator that is impregnated with an electrolyte between the aluminum anode foil and the cathode. This construction gives the device its electrolytic double layer charge storage capability, which enables it to store electrical energy in the form of electrostatic charge.

Specifications of the 420KXW82MEFC18X25

The 420KXW82MEFC18X25 aluminum electrolytic capacitor is designed to offer high performance with a thin and compact design. The capacitor is rated for a temperature range from -40°C to +125°C, can hold a maximum working voltage of 16V and has a life expectancy of 1000 hours at +105°C. The capacitance range is between 0.33µF and 4.7µF, and the part number measures 5.2mm in diameter by 8.2mm in length.

Application Field and Working Principle of the 420KXW82MEFC18X25

Aluminum electrolytic capacitors are used in a wide range of applications, including filtering, decoupling, buffering, smoothing, blocking, coupling, timing, temperature compensation and more. The 420KXW82MEFC18X25 is specifically designed for general circuit applications.In terms of operation, when the capacitor is connected to an alternating current (AC) circuit, an electrostatic charge is caused to exist on the anode and cathode due to their two different forms of electrodes. As a result, energy is stored in the capacitor’s dielectric layer and is released when needed, thereby playing a role in filtering and decoupling.

Conclusion

The 420KXW82MEFC18X25 aluminum electrolytic capacitor is a device designed to be used for general circuit applications, offering high performance with a thin and compact design. It is one of many aluminum electrolytic capacitors in the market today, each one providing their own distinct features and performance levels. This article has provided an overview of the 420KXW82MEFC18X25 and its important features, and how it fits into the aluminum electrolytic capacitor category.
