Aluminum Electrolytic CapacitorsAn aluminum electrolytic capacitor, also known as an electrochemical capacitor, is an electronic component that is widely used in commercial and industrial applications to store energy in electrical circuits. This type of capacitor has available capacitance values ranging from very small to very large, depending on the application.The B43540A5397M007 is an aluminum electrolytic capacitor, specifically a radial dipped type, with a capacitance of 4.7mF and an operating temperature range of -40°C to +125°C. The capacitor is especially suitable for applications down to -55°C, making it suitable for use in extreme temperature applications, such as defrosting compressors and solar panels.The working principle of an aluminum electrolytic capacitor is based on the principle of electrolysis. This is the process of passing an electric current through an electrolyte, causing ions to travel between two poles. The electric current causes an anode to form on the positive side of the electrolyte and a cathode to form on the negative side. The anode is made from a metal foil, and the cathode is made from a special paper material that is soaked with an electrolyte solution.The electric current passing through the electrolyte causes a layer of aluminum oxide to form on the surface of the aluminum foil anode. This aluminum oxide layer acts as an insulating barrier that prevents electrically charged ions from passing through it, thus forming a capacitance element. This capacitance element contributes to the capacitance of the capacitor, allowing it to store energy and discharge it when necessary.The B43540A5397M007 aluminum electrolytic capacitor can be used as a buffer capacitor in power circuits, or for DC-link voltage regulation and power factor correction in AC applications. It is also suitable for use in combination with a self-healing type in frequency converters, motor control, light circuits, anti-interference circuits, and many other power supply systems.The radial dipped design of the B43540A5397M007 allows for a compact, low-profile form factor. It has a low-impedance construction and is designed to provide long life and high reliability, with a rated life of 5000hrs.The B43540A5397M007 aluminum electrolytic capacitor is a robust and reliable device, offering a wide operating temperature range and excellent performance. It is suitable for a variety of applications in the industrial and commercial markets, and can offer a highly effective solution for applications where low impedance and high capacitance are required.
