Aluminum Electrolytic Capacitors: 160NXA0.47MEFC5X11 Application Field and Working Principle

Aluminum electrolytic capacitors are an essential component in many electronics and electrical applications across the world and they are a relatively inexpensive, yet reliable component. The specific type considered in this article is the 160NXA0.47MEFC5X11, which is a radial lead, surface-mount aluminum electrolytic capacitor.

Design and Application

The 160NXA0.47MEFC5X11 capacitor is a small, radial leaded component with a maximum case size of 5mm x 11mm. This component is a surface mount capacitor with a thickness of 1.8mm and two leads are spaced approximately 4.5mm apart. It has a capacitance of 0.47µF and a voltage rating of 16 V. It is designed for use in a wide variety of consumer, commercial and industrial applications such as telecom, automotive, medical, computers, and lighting.

Construction

The 160NXA0.47MEFC5X11 is an aluminum electrolytic capacitor consisting of two electrical conductors separated by an insulating dielectric material known as an electrolyte. The capacitor is constructed of two thin aluminum foil electrodes coated with an oxide layer, a spacer material, and an electrolyte. The two aluminum electrodes are rolled up and housed in a cylindrical or cylindrical shaped can. The anode and cathode terminals of the capacitor are then connected to the leads of the capacitor.

Working Principle

When a voltage is applied between the two electrodes of the aluminum electrolytic capacitor, the positive charge from the voltage causes the positive ions in the electrolyte to form an electric double layer on the aluminum foil surface. This electric double layer creates a potential barrier between the two electrodes and thus prevents the current from flowing between them. The capacitance of the 160NXA0.47MEFC5X11 is determined by the amount of surface area between the two electrodes, which is determined by the thickness of the dielectric material (electrolyte) layer.

Advantages of the 160NXA0.47MEFC5X11

The 160NXA0.47MEFC5X11 aluminum electrolytic capacitor provides several distinct advantages over traditional capacitors. One of the primary advantages is the very small size of the component which allows for its use in tight spaces. It has a low ESR (Equivalent Series Resistance) which indicates a high quality and efficient capacitor. It also has an extremely low leakage current which helps ensure reliable operation. The thin oxide layer on the aluminum foil also ensures a low dielectric absorption rate.

Conclusion

The 160NXA0.47MEFC5X11 aluminum electrolytic capacitor is a reliable, efficient capacitor designed for use in a variety of consumer, commercial and industrial applications. It offers several advantages over traditional capacitors, such as a very small size, low ESR, low leakage current, and low dielectric absorption rate. The capacitor is constructed from two thin aluminum foil electrodes coated with an oxide layer, a spacer material, and an electrolyte. Its capacitance is determined by the amount of surface area in between the two electrodes.
