Aluminum electrolytic capacitors (AECs) are extremely popular components in electronic circuits, due to their inexpensive cost, excellent performance, and excellent energy storage capabilities. They have been used in various applications, including audio, automotive, and LED lighting. The B43508E2188M7 capacitor is an AEC designed for a range of industrial applications. Its features and working principle are as follows.

Features

This AEC has a wide range of features which make it particularly useful in industrial applications. It is rated at an operating temperature of -40℃ to +125℃, has an excellent ripple voltage tolerance of 85VAC, and also comes with a long shelf life of 5000 hours. It also has a rated capacitance of 2.2μF, a low equivalent series resistance (ESR) of 45mΩ, and a long-term lifespan of 1000 hours. Furthermore, it is 100% RoHS compliant, which means it is lead and hazardous substance free.

Working Principle

The working principle of an AEC is based on the principle of electrolysis. It consists of a positive two-layer aluminum foil anode, a separator, a negative one-layer aluminum foil cathode, and an electrolyte. When a voltage is applied, the anode and cathode layers form into pockets which are filled with electrolyte. This creates an electric field between the two layers, which stores the charge and allows electric current to flow. The stored charge can then be released when desired. AECs are able to store much higher levels of energy than traditional capacitors, making them very useful in a variety of applications.

Application Fields

The B43508E2188M7 AEC is designed for use in a wide variety of industrial applications. It is ideal for high frequency power switching applications due to its excellent ripple voltage tolerance, low ESR, and long-term stability. It is also suitable for controlling noise in electronic circuits as well as for switching-mode power supplies, motor control applications, SMPS, and AC adaptors. Furthermore, this capacitor is also ideal for temperature-sensitive applications due to its operating temperature range of -40℃ to +125℃.

Conclusion

The B43508E2188M7 aluminum electrolytic capacitor is an excellent choice for a range of industrial applications due to its wide range of features and good performance.
